Barbara Betlejewska is a PR consultant and manager with extensive experience in architecture and real estate, currently involved with World Visualization Festival, a global event bringing together CGI and digital storytelling professionals for 3 days of presentations, workshops, and networking in Warsaw, Poland, this October. Over the last twenty years, visualization and 3D rendering have evolved from supporting tools to become central pillars of architectural storytelling, design development, and marketing across various industries. As digital technologies have advanced, the landscape of creative work has changed dramatically. Artists can now collaborate with clients worldwide without leaving their homes, and their careers can flourish without ever setting foot in a traditional studio. In this hyper-connected world, where access to knowledge, clients, and inspiration is just a click away, do we still need to gather in person? Do conferences, festivals and meetups in the CGI and architectural visualization world still carry weight? The People Behind the Pixels Professionals from the visualization industry exchanging ideas at WVF 2024. For a growing number of professionals — especially those in creative and tech-driven fields — remote work has become the norm. The shift to digital workflows, accelerated by the pandemic, has brought freedom and flexibility that many are reluctant to give up. It’s easier than ever to work for clients in distant cities or countries, to build a freelance career from a laptop, or to pursue the lifestyle of a digital nomad. On the surface, it is a broadening of horizons. But for many, the freedom of remote work comes with a cost: isolation. For visualization artists, the reality often means spending long hours alone, rarely interacting face-to-face with peers or collaborators. And while there are undeniable advantages to independent work, the lack of human connection can lead to creative stagnation, professional burnout, and a sense of detachment from the industry as a whole. Despite being a highly technical and often solitary craft, visualization and CGI thrive on the exchange of ideas, feedback and inspiration. The tools and techniques evolve rapidly, and staying relevant usually means learning not just from tutorials but from honest conversations with others who understand the nuances of the field. A Community in the Making Professionals from the visualization industry exchanging ideas at WVF 2024. That need for connection is what pushed Michał Nowak, a Polish visualizer and founder of Nowak Studio, to organize Poland’s first-ever architectural visualization meetup in 2017. With no background in event planning, he wasn’t sure where to begin, but he knew something was missing. The Polish Arch Viz scene lacked a shared space for meetings, discussions, and idea exchange. Michał wanted more than screen time; he wanted honest conversations, spontaneous collaboration and a chance to grow alongside others in the field. What began as a modest gathering quickly grew into something much bigger. That original meetup evolved into what is now the World Visualization Festival (WVF), an international event that welcomes artists from across Europe and beyond. “I didn’t expect our small gathering to grow into a global festival,” Michał says. “But I knew I wanted a connection. I believed that through sharing ideas and experiences, we could all grow professionally, creatively, and personally. And that we’d enjoy the journey more.” The response was overwhelming. Each year, more artists from across Poland and Europe join the event in Wrocław, located in south-western Poland. Michał also traveled to other festivals in countries like Portugal and Austria, where he observed the same thing: a spirit of openness, generosity, and shared curiosity. No matter the country or the maturity of the market, the needs were the same — people wanted to connect, learn and grow. And beyond the professional side, there was something else: joy. These events were simply fun. They were energizing. They gave people a reason to step away from their desks and remember why they love what they do. The Professional Benefits Hands-on learning at the AI-driven visualization workshop in Warsaw, October 2024. The professional benefits of attending industry events are well documented. These gatherings provide access to mentorship, collaboration and knowledge that can be challenging to find online. Festivals and industry meetups serve as platforms for emerging trends, new tools and fresh workflows — often before they hit the mainstream. They’re places where ideas collide, assumptions are challenged and growth happens. The range of topics covered at such events is broad, encompassing everything from portfolio reviews and in-depth discussions of particular rendering engines to discussions about pricing your work and building a sustainable business. At the 2024 edition of the World Visualization Festival, panels focused on scaling creative businesses and navigating industry rates drew some of the biggest crowds, proving that artists are hungry for both artistic and entrepreneurial insights. Being part of a creative community also shapes professional identity. It’s not just about finding clients — it’s about finding your place. In a field as fast-moving and competitive as Arch Viz, connection and conversation aren’t luxuries. They’re tools for survival. There’s also the matter of building your social capital. Online interactions can only go so far. Meeting someone in person builds relationships that stick. The coffee-break conversations, the spontaneous feedback — these are the moments that cement a community and have the power to spark future projects or long-lasting partnerships. This usually doesn’t happen in Zoom calls. And let’s not forget the symbolic power of events like industry awards, such as the Architizer’s Vision Awards or CGArchitect’s 3D Awards. These aren’t just celebrations of talent; they’re affirmations of the craft itself. They contribute to the growth and cohesion of the industry while helping to establish and promote best practices. These events clearly define the role and significance of CGI and visualization as a distinct profession, positioned at the intersection of architecture, marketing, and sales. They advocate for the field to be recognized on its own terms, not merely as a support service, but as an independent discipline. For its creators, they bring visibility, credit, and recognition — elements that inspire growth and fuel motivation to keep pushing the craft forward. Occasions like these remind us that what we do has actual value, impact and meaning. The Energy We Take Home The WVF 2024 afterparty provided a vibrant space for networking and celebration in Warsaw. Many artists describe the post-event glow: a renewed sense of purpose, a fresh jolt of energy, an eagerness to get back to work. Sometimes, new projects emerge, new clients appear, or long-dormant ideas finally gain momentum. These events aren’t just about learning — they’re about recharging. One of the most potent moments of last year’s WVF was a series of talks focused on mental health and creative well-being. Co-organized by Michał Nowak and the Polish Arch Viz studio ELEMENT, the festival addressed the emotional realities of the profession, including burnout, self-doubt, and the pressure to constantly produce. These conversations resonated deeply because they were real. Seeing that others face the same struggles — and come through them — is profoundly reassuring. Listening to someone share a business strategy that worked, or a failure they learned from, turns competition into camaraderie. Vulnerability becomes strength. Shared experiences become the foundation of resilience. Make a Statement. Show up! Top industry leaders shared insights during presentations at WVF 2024 In an era when nearly everything can be done online, showing up in person is a powerful statement. It says: I want more than just efficiency. I want connection, creativity and conversation. As the CGI and visualization industries continue to evolve, the need for human connection hasn’t disappeared — it’s grown stronger. Conferences, festivals and meetups, such as World Viz Fest, remain vital spaces for knowledge sharing, innovation and community building. They give us a chance to reset, reconnect and remember that we are part of something bigger than our screens. So, yes, despite the tools, the bandwidth, and the ever-faster workflows, we still need to meet in person. Not out of nostalgia, but out of necessity. Because, no matter how far technology takes us, creativity remains a human endeavor. Architizer’s Vision Awards are back! The global awards program honors the world’s best architectural concepts, ideas and imagery. Start your entry ahead of the Final Entry Deadline on July 11th.  The post Building an Architectural Visualization Community: The Case for Physical Gatherings appeared first on Journal.

When Leta Sobierajski enrolled in college, she already knew what she was meant to do, and she didn’t settle for anything less. “When I went to school for graphic design, I really didn’t have a backup plan – it was this, or nothing,” she says. “My work is a constantly evolving practice, and from the beginning, I have always convinced myself that if I put in the time and experimentation, I would grow and evolve.” After graduation, Sobierajski took on a range of projects, which included animation, print, and branding elements. She collaborated with corporate clients, but realized that she wouldn’t feel comfortable following anyone else’s rules in a 9-to-5 environment. Leta Sobierajski (standing) and Wade Jeffree (on ladder) \\\ Photo: Matt Dutile Sobierajski eventually decided to team up with fellow artist and kindred spirit Wade Jeffree. In 2016 they launched their Brooklyn-based studio, Wade and Leta. The duo, who share a taste for quirky aesthetics, produces sculpture, installations, or anything else they can dream up. Never static in thinking or method, they are constantly searching for another medium to try that will complement their shared vision of the moment. The pair is currently interested in permanency, and they want to utilize more metal, a strong material that will stand the test of time. Small architectural pieces are also on tap, and on a grander scale, they’d like to focus on a park or communal area that everyone can enjoy. With so many ideas swirling around, Sobierajski will record a concept in at least three different ways so that she’s sure to unearth it at a later date. “In some ways, I like to think I’m impeccably organized, as I have countless spreadsheets tracking our work, our lives, and our well-being,” she explains. “The reality is that I am great at over-complicating situations with my intensified list-making and note-taking. The only thing to do is to trust the process.” Today, Leta Sobierajski joins us for Friday Five! Photo: Melitta Baumeister and Michał Plata 1. Melitta Baumeister and Michał Plata The work of Melitta Baumeister and Michał Plata has been a constant inspiration to me for their innovative, artful, and architectural silhouettes. By a practice of draping and arduous pattern-making, the garments that they develop season after season feel like they could be designed for existence in another universe. I’m a person who likes to dress up for anything when I’m not in the studio, and every time I opt to wear one of their looks, I feel like I can take on the world. The best part about their pieces is that they’re extremely functional, so whether I need to hop on a bicycle or show up at an opening, I’m still able to make a statement – these garments even have the ability to strike up conversations on their own. Photo: Wade and Leta 2. Pandas! I was recently in Chengdu to launch a new project and we took half the day to visit the Chengdu Research Base of Giant Pandas and I am a new panda convert. Yes, they’re docile and cute, but their lifestyles are utterly chill and deeply enviable for us adults with responsibilities. Giant pandas primarily eat bamboo and can consume 20-40 kilograms per day. When they’re not doing that, they’re sleeping. When we visited, many could be seen reclining on their backs, feasting on some of the finest bamboo they could select within arm’s reach. While not necessarily playful in appearance, they do seem quite cheeky in their agendas and will do as little as they can to make the most of their meals. It felt like I was watching a mirrored image of myself on a Sunday afternoon while trying to make the most of my last hours of the weekend. Photo: Courtesy of Aoiro 3. Aoiro I’m not really a candle person (I forget to light it, and then I forget it’s lit, and then I panic when it’s been lit for too long) but I love the luxurious subtlety of a fragrant space. It’s an intangible feeling that really can only be experienced in the present. Some of the best people to create these fragrances, in my opinion, are Shizuko and Manuel, the masterminds behind Aoiro, a Japanese and Austrian duo who have developed a keen sense for embodying the fragrances of some of the most intriguing and captivating olfactory atmospheres – earthy forest floors with crackling pine needles, blue cypress tickling the moon in an indigo sky, and rainfall on a spirited Japanese island. Despite living in an urban city, Aoiro’s olfactory design is capable of transporting me to the deepest forests of misty Yakushima island. Photo: Wade and Leta 4. Takuro Kuwata A few months ago, I saw the work of Japanese ceramicist Takuro Kuwata at an exhibition at Salon94 and have been having trouble getting it out of my head. Kuwata’s work exemplifies someone who has worked with a medium so much to completely use the medium as a medium – if that makes sense. His ability to manipulate clay and glaze and use it to create gravity-defying effects within the kiln are exceptionally mysterious to me and feel like they could only be accomplished with years and years of experimentation with the material. I’m equally impressed seeing how he’s grown his work with scale, juxtaposing it with familiar iconography like the fuzzy peach, but sculpting it from materials like bronze. Photo: Wade and Leta 5. The Site of Reversible Destiny, a park built by artists Arakawa and Gins, in Yoro Japan The park is a testament to their career as writers, architects, and their idea of reversible destiny, which in its most extreme form, eliminates death. For all that are willing to listen, Arakawa and Gins’ Reversible Destiny mentality aims to make our lives a little more youthful by encouraging us to reevaluate our relationship with architecture and our surroundings. The intention of “reversible destiny” is not to prolong death, postpone it, grow older alongside it, but to entirely not acknowledge and surpass it. Wade (my partner) and I have spent the last ten years traveling to as many of their remaining sites as possible to further understand this notion of creating spaces to extend our lives and question how conventional living spaces can become detrimental to our longevity.   Works by Wade and Leta: Photo: Wade and Leta and Matt Alexander Now You See Me is a large-scale installation in the heart of Shoreditch, London, that explores the relationship between positive and negative space through bold color, geometry, and light. Simple, familiar shapes are embedded within monolithic forms, creating a layered visual experience that shifts throughout the day. As sunlight passes through the structures, shadows and silhouettes stretch and connect, forming dynamic compositions on the surrounding concrete. Photo: Wade and Leta and John Wylie Paint Your Own Path is series of five towering sculptures, ranging from 10 to 15 feet tall, invites viewers to explore balance, tension, and perspective through bold color and form. Inspired by the delicate, often precarious act of stacking objects, the sculptures appear as if they might topple – yet each one holds steady, challenging perceptions of stability. Created in partnership with the Corolla Cross, the installation transforms its environment into a pop-colored landscape. Photo: Millenia Walk and Outer Edit, Eurthe Studio Monument to Movement is a 14-meter-tall kinetic sculpture that celebrates the spirit of the holiday season through rhythm, motion, and color. Rising skyward in layered compositions, the work symbolizes collective joy, renewal, and the shared energy of celebrations that span cultures and traditions. Powered by motors and constructed from metal beams and cardboard forms, the sculpture continuously shifts, inviting viewers to reflect on the passage of time and the cycles that connect us all. Photo: Wade and Leta and Erika Hara, Piotr Maslanka, and Jeremy Renault Falling Into Place is a vibrant rooftop installation at Ginza Six that explores themes of alignment, adaptability, and perspective. Six colorful structures – each with a void like a missing puzzle piece – serve as spaces for reflection, inviting visitors to consider their place within a greater whole. Rather than focusing on absence, the design transforms emptiness into opportunity, encouraging people to embrace spontaneity and the unfolding nature of life. Playful yet contemplative, the work emphasizes that only through connection and participation can the full picture come into view. Photo: Wade and Leta and Erika Hara, Piotr Maslanka, and Jeremy Renault Photo: Wade and Leta Stop, Listen, Look is a 7-meter-tall interactive artwork atop IFS Chengdu that captures the vibrant rhythm of the city through movement, sound, and form. Blending motorized and wind-powered elements with seesaws and sound modulation, it invites people of all ages to engage, play, and reflect. Inspired by Chengdu’s balance of tradition and modernity, the piece incorporates circular motifs from local symbolism alongside bold, geometric forms to create a dialogue between past and present. With light, motion, and community at its core, the work invites visitors to connect with the city – and each other – through shared interaction. The Cloud is a permanent sculptural kiosk in Burlington, Vermont’s historic City Hall Park, created in collaboration with Brooklyn-based Studio RENZ+OEI. Designed to reinterpret the ephemeral nature of clouds through architecture, it blends art, air, and imagination into a light, fluid structure that defies traditional rigidity. Originally born from a creative exchange between longtime friends and collaborators, the design challenges expectations of permanence by embodying movement and openness. Now home to a local food vendor, The Cloud brings a playful, uplifting presence to the park, inviting reflection and interaction rain or shine..

monkey abuse The “online monkey torture video” arrests just keep coming Authorities continue the slow crackdown. Nate Anderson – Jun 14, 2025 7:00 am | 34 Credit: Getty Images Credit: Getty Images Story text Size Small Standard Large Width * Standard Wide Links Standard Orange * Subscribers only   Learn more Today's monkey torture videos are the products of a digitally connected world. People who enjoy watching baby animals probed, snipped, and mutilated in horrible ways often have difficulty finding local collaborators, but online communities like "million tears"—now thankfully shuttered—can help them forge connections. Once they do meet other like-minded souls, communication takes place through chat apps like Telegram and Signal, often using encryption. Money is pooled through various phone apps, then sent to videographers in countries where wages are low and monkeys are plentiful. (The cases I have seen usually involve Indonesia; read my feature from last year to learn more about how these groups work.) There, monkeys are tortured by a local subcontractor—sometimes a child—working to Western specs. Smartphone video of the torture is sent back to the commissioning sadists, who share it with more viewers using the same online communities in which they met. The unfortunate pattern was again on display this week in an indictment the US government unsealed against several more Americans said to have commissioned these videos. The accused used online handles like "Bitchy" and "DemonSwordSoulCrusher," and they hail from all over: Tennessee, North Carolina, Ohio, Pennsylvania, and Massachusetts. They relied on an Indonesian videographer to create the content, which was surprisingly affordable—it cost a mere $40 to commission video of a "burning hot screwdriver" being shoved into a baby monkey's orifice. After the money was transferred, the requested video was shot and shared through a "phone-based messaging program," but the Americans were deeply disappointed in its quality. Instead of full-on impalement, the videographer had heated a screwdriver on a burner and merely touched it against the monkey a few times. "So lame," one of the Americans allegedly complained to another. "Live and learn," was the response. So the group tried again. "Million tears" had been booted by its host, but the group reconstituted on another platform and renamed itself "the trail of trillion tears." They reached out to another Indonesian videographer and asked for a more graphic version of the same video. But this version, more sadistic than the last, still didn't satisfy. As one of the Americans allegedly said to another, "honey that's not what you asked for. Thats the village idiot version. But I'm talking with someone about getting a good vo [videographer] to do it." Arrests continue In 2021, someone leaked communications from the "million tears" group to animals rights organizations like Lady Freethinker and Action for Primates, which handed it over to authorities. Still, it took several years to arrest and prosecute the torture group's leaders. In 2024, one of these leaders—Ronald Bedra of Ohio—pled guilty to commissioning the videos and to mailing "a thumb drive containing 64 videos of monkey torture to a co-conspirator in Wisconsin." His mother, in a sentencing letter to the judge, said that her son must "have been undergoing some mental crisis when he decided to create the website." As a boy, he had loved all of the family pets, she said, even providing a funeral for a fish. Bedra was sentenced late last year to 54 months in prison. According to letters from family members, he has also lost his job, his wife, and his kids. In April 2025, two more alleged co-conspirators were indicted and subsequently arrested; their cases were unsealed only this week. Two other co-conspirators from this group still appear to be uncharged. In May 2025, 11 other Americans were indicted for their participation in monkey torture groups, though they appear to come from a different network. This group allegedly "paid a minor in Indonesia to commit the requested acts on camera." As for the Indonesian side of this equation, arrests have been happening there, too. Following complaints from animal rights groups, police in Indonesia have arrested multiple videographers over the last two years.

Solar air heating is among the most cost-effective applications of solar thermal energy. These systems are used for space heating and preheating fresh air for ventilation, typically using glazed or unglazed perforated solar collectors. The collectors draw in outside air, heat it using solar energy, and then distribute it through ductwork to meet building heating and fresh air needs. In 2024, Canada led again the world for the at least seventh year in a row in solar air heating adoption. The four key suppliers – Trigo Energies, Conserval Engineering, Matrix Energy, and Aéronergie – reported a combined 26,203 m2 (282,046 ft2) of collector area sold last year. Several of these providers are optimistic about the growing demand. These findings come from the newly released Canadian Solar Thermal Market Survey 2024, commissioned by Natural Resources Canada. Canada is the global leader in solar air heating. The market is driven by a strong network of experienced system suppliers, optimized technologies, and a few small favorable funding programs – especially in the province of Quebec. Architects and developers are increasingly turning to these cost-effective, façade-integrated systems as a practical solution for reducing onsite natural gas consumption. Despite its cold climate, Canada benefits from strong solar potential with solar irradiance in many areas rivaling or even exceeding that of parts of Europe. This makes solar air heating not only viable, but especially valuable in buildings with high fresh air requirements including schools, hospitals, and offices. The projects highlighted in this article showcase the versatility and relevance of solar air heating across a range of building types, from new constructions to retrofits. Figure 1: Preheating air for industrial buildings: 2,750 m2 (29,600 ft2) of Calento SL solar air collectors cover all south-west and south-east facing facades of the FAB3R factory in Trois-Rivières, Quebec. The hourly unitary flow rate is set at 41 m3/m2 or 2.23 cfm/ft2 of collector area, at the lower range because only a limited number of intake fans was close enough to the solar façade to avoid long ventilation ductwork. Photo: Trigo Energies Quebec’s solar air heating boom: the Trigo Energies story Trigo Energies makes almost 90 per cent of its sales in Quebec. “We profit from great subsidies, as solar air systems are supported by several organizations in our province – the electricity utility Hydro Quebec, the gas utility Energir and the Ministry of Natural Resources,” explained Christian Vachon, Vice President Technologies and R&D at Trigo Energies. Trigo Energies currently has nine employees directly involved in planning, engineering and installing solar air heating systems and teams up with several partner contractors to install mostly retrofit projects. “A high degree of engineering is required to fit a solar heating system into an existing factory,” emphasized Vachon. “Knowledge about HVAC engineering is as important as experience with solar thermal and architecture.” One recent Trigo installation is at the FAB3R factory in Trois-Rivières. FAB3R specializes in manufacturing, repairing, and refurbishing large industrial equipment. Its air heating and ventilation system needed urgent renovation because of leakages and discomfort for the workers. “Due to many positive references he had from industries in the area, the owner of FAB3R contacted us,” explained Vachon. “The existence of subsidies helped the client to go for a retrofitting project including solar façade at once instead of fixing the problems one bit at a time.” Approximately 50 per cent of the investment costs for both the solar air heating and the renovation of the indoor ventilation system were covered by grants and subsidies. FAB3R profited from an Energir grant targeted at solar preheating, plus an investment subsidy from the Government of Quebec’s EcoPerformance Programme.   Blue or black, but always efficient: the advanced absorber coating In October 2024, the majority of the new 2,750 m² (29,600 ft2) solar façade at FAB3R began operation (see figure 1). According to Vachon, the system is expected to cover approximately 13 per cent of the factory’s annual heating demand, which is otherwise met by natural gas. Trigo Energies equipped the façade with its high-performance Calento SL collectors, featuring a notable innovation: a selective, low-emissivity coating that withstands outdoor conditions. Introduced by Trigo in 2019 and manufactured by Almeco Group from Italy, this advanced coating is engineered to maximize solar absorption while minimizing heat loss via infrared emission, enhancing the overall efficiency of the system. The high efficiency coating is now standard in Trigo’s air heating systems. According to the manufacturer, the improved collector design shows a 25 to 35 per cent increase in yield over the former generation of solar air collectors with black paint. Testing conducted at Queen’s University confirms this performance advantage. Researchers measured the performance of transpired solar air collectors both with and without a selective coating, mounted side-by-side on a south-facing vertical wall. The results showed that the collectors with the selective coating produced 1.3 to 1.5 times more energy than those without it. In 2024, the monitoring results were jointly published by Queen’s University and Canmat Energy in a paper titled Performance Comparison of a Transpired Air Solar Collector with Low-E Surface Coating. Selective coating, also used on other solar thermal technologies including glazed flat plate or vacuum tube collectors, has a distinctive blue color. Trigo customers can, however, choose between blue and black finishes. “By going from the normal blue selective coating to black selective coating, which Almeco is specially producing for Trigo, we lose about 1 per cent in solar efficiency,” explained Vachon.

Photo: Matrix Energy Matrix Energy: collaborating with architects and engineers in new builds The key target customer group of Matrix Energy are public buildings – mainly new construction. “Since the pandemic, schools are more conscious about fresh air, and solar preheating of the incoming fresh air has a positive impact over the entire school year,” noted Brian Wilkinson, President of Matrix Energy. Matrix Energy supplies systems across Canada, working with local partners to source and process the metal sheets used in their MatrixAir collectors. These metal sheets are perforated and then formed into architectural cladding profiles. The company exclusively offers unglazed, single-stage collectors, citing fire safety concerns associated with polymeric covers. “We have strong relationships with many architects and engineers who appreciate the simplicity and cost-effectiveness of transpired solar air heating systems,” said President Brian Wilkinson, describing the company’s sales approach. “Matrix handles system design and supplies the necessary materials, while installation is carried out by specialized cladding and HVAC contractors overseen by on-site architects and engineers,” Wilkinson added. Finding the right flow: the importance of unitary airflow rates One of the key design factors in solar air heating systems is the amount of air that passes through each square meter of the perforated metal absorber,  known as the unitary airflow rate. The principle is straightforward: higher airflow rates deliver more total heat to the building, while lower flow rates result in higher outlet air temperatures. Striking the right balance between air volume and temperature gain is essential for efficient system performance. For unglazed collectors mounted on building façades, typical hourly flow rates should range between 120 and 170 (m3/h/m2), or 6.6 to 9.4 cfm/ft2. However, Wilkinson suggests that an hourly airflow rate of around 130 m³/h/m² (7.2 cfm/ft2) offers the best cost-benefit balance for building owners. If the airflow is lower, the system will deliver higher air temperatures, but it would then need a much larger collector area to achieve the same air volume and optimum performance, he explained. It’s also crucial for the flow rate to overcome external wind pressure. As wind passes over the absorber, air flow through the collector’s perforations is reduced, resulting in heat losses to the environment. This effect becomes even more pronounced in taller buildings, where wind exposure is greater. To ensure the system performs well even in these conditions, higher hourly airflow rates typically between 150 and 170 m³/m² (8.3 to 9.4 cfm/ft2)  are necessary.

Photo: Conserval Engineering Solar air heating systems support LEED-certified building designs Solar air collectors are also well-suited for use in multi-unit residential buildings. A prime example is the Canary District in Toronto (see Figure 3), where single-stage SolarWall collectors from Conserval Engineering have been installed on several MURBs to clad the mechanical penthouses. “These penthouses are an ideal location for our air heating collectors, as they contain the make-up air units that supply corridor ventilation throughout the building,” explained Victoria Hollick, Vice President of Conserval Engineering. “The walls are typically finished with metal façades, which can be seamlessly replaced with a SolarWall system – maintaining the architectural language without disruption.” To date, nine solar air heating systems have been commissioned in the Canary District, covering a total collector area of over 1,000 m² (10,764 ft2). “Our customers have many motivations to integrate SolarWall technology into their new construction or retrofit projects, either carbon reduction, ESG, or green building certification targets,” explained Hollick. The use of solar air collectors in the Canary District was proposed by architects from the Danish firm Cobe. The black-colored SolarWall system preheats incoming air before it is distributed to the building’s corridors and common areas, reducing reliance on natural gas heating and supporting the pursuit of LEED Gold certification. Hollick estimates the amount of gas saved between 10 to 20 per cent of the total heating load for the corridor ventilation of the multi-unit residential buildings. Additional energy-saving strategies include a 50/50 window-to-wall ratio with high-performance glazing, green roofs, high-efficiency mechanical systems, LED lighting, and Energy Star-certified appliances. The ideal orientation for a SolarWall system is due south. However, the systems can be built at any orientation up to 90° east and west, explained Hollick. A SolarWall at 90° would have approximately 60 per cent of the energy production of the same area facing south.Canada’s expertise in solar air heating continues to set a global benchmark, driven by supporting R&D, by innovative technologies, strategic partnerships, and a growing portfolio of high-impact projects. With strong policy support and proven performance, solar air heating is poised to play a key role in the country’s energy-efficient building future.

ILM teams with Ben Stiller and Apple TV+ to bring thousands of seamless visual effects shots to the hit drama’s second season. By Clayton Sandell There are mysterious and important secrets to be uncovered in the second season of the wildly popular Apple TV+ series Severance (2022-present). About 3,500 of them are hiding in plain sight. That’s roughly the number of visual effects shots helping tell the Severance story over 10 gripping episodes in the latest season, a collaborative effort led by Industrial Light & Magic. ILM’s Eric Leven served as the Severance season two production visual effects supervisor. We asked him to help pull back the curtain on some of the show’s impressive digital artistry that most viewers will probably never notice. “This is the first show I’ve ever done where it’s nothing but invisible effects,” Leven tells ILM.com. “It’s a really different calculus because nobody talks about them. And if you’ve done them well, they are invisible to the naked eye.” With so many season two shots to choose from, Leven helped us narrow down a list of his favorite visual effects sequences to five. (As a bonus, we’ll also dive into an iconic season finale shot featuring the Mr. Milchick-led marching band.) Before we dig in, a word of caution. This article contains plot spoilers for Severance. (And in case you’re already wondering: No, the goats are not computer-graphics.) Severance tells the story of Mark Scout (Adam Scott), department chief of the secretive Severed Floor located in the basement level of Lumon Industries, a multinational biotech corporation. Mark S., as he’s known to his co-workers, heads up Macrodata Refinement (MDR), a department where employees help categorize numbers without knowing the true purpose of their work.  Mark and his team – Helly R. (Britt Lower), Dylan G. (Zach Cherry), and Irving B. (John Turturro), have all undergone a surgical procedure to “sever” their personal lives from their work lives. The chip embedded in their brains effectively creates two personalities that are sometimes at odds: an “Innie” during Lumon office hours and an “Outie” at home. “This is the first show I’ve ever done where it’s nothing but invisible effects. It’s a really different calculus because nobody talks about them. And if you’ve done them well, they are invisible to the naked eye.”Eric Leven 1. The Running Man (Episode 201: “Hello, Ms. Cobel”) The season one finale ends on a major cliffhanger. Mark S. learns that his Outie’s wife, Gemma – believed killed in a car crash years ago – is actually alive somewhere inside the Lumon complex. Season two opens with Mark S. arriving at the Severed Floor in a desperate search for Gemma, who he only knows as her Innie persona, Ms. Casey. The fast-paced sequence is designed to look like a single, two-minute shot. It begins with the camera making a series of rapid and elaborate moves around a frantic Mark S. as he steps out of the elevator, into the Severed Floor lobby, and begins running through the hallways. “The nice thing about that sequence was that everyone knew it was going to be difficult and challenging,” Leven says, adding that executive producer and Episode 201 director, Ben Stiller, began by mapping out the hallway run with his team. Leven recommended that a previsualization sequence – provided by The Third Floor – would help the filmmakers refine their plan before cameras rolled. “While prevising it, we didn’t worry about how we would actually photograph anything. It was just, ‘These are the visuals we want to capture,’” Leven says. “‘What does it look like for this guy to run down this hallway for two minutes? We’ll figure out how to shoot it later.’” The previs process helped determine how best to shoot the sequence, and also informed which parts of the soundstage set would have to be digitally replaced. The first shot was captured by a camera mounted on a Bolt X Cinebot motion-control arm provided by The Garage production company. The size of the motion-control setup, however, meant it could not fit in the confined space of an elevator or the existing hallways. “We couldn’t actually shoot in the elevator,” Leven says. “The whole elevator section of the set was removed and was replaced with computer graphics [CG].” In addition to the elevator, ILM artists replaced portions of the floor, furniture, and an entire lobby wall, even adding a reflection of Adam Scott into the elevator doors. As Scott begins running, he’s picked up by a second camera mounted on a more compact, stabilized gimbal that allows the operator to quickly run behind and sometimes in front of the actor as he darts down different hallways. ILM seamlessly combined the first two Mark S. plates in a 2D composite. “Part of that is the magic of the artists at ILM who are doing that blend. But I have to give credit to Adam Scott because he ran the same way in both cameras without really being instructed,” says Leven. “Lucky for us, he led with the same foot. He used the same arm. I remember seeing it on the set, and I did a quick-and-dirty blend right there and thought, ‘Oh my gosh, this is going to work.’ So it was really nice.” The action continues at a frenetic pace, ultimately combining ten different shots to complete the sequence. “We didn’t want the very standard sleight of hand that you’ve seen a lot where you do a wipe across the white hallway,” Leven explains. “We tried to vary that as much as possible because we didn’t want to give away the gag. So, there are times when the camera will wipe across a hallway, and it’s not a computer graphics wipe. We’d hide the wipe somewhere else.” A slightly more complicated illusion comes as the camera sweeps around Mark S. from back to front as he barrels down another long hallway. “There was no way to get the camera to spin around Mark while he is running because there’s physically not enough room for the camera there,” says Leven. To capture the shot, Adam Scott ran on a treadmill placed on a green screen stage as the camera maneuvered around him. At that point, the entire hallway environment is made with computer graphics. Artists even added a few extra frames of the actor to help connect one shot to the next, selling the illusion of a single continuous take. “We painted in a bit of Adam Scott running around the corner. So if you freeze and look through it, you’ll see a bit of his heel. He never completely clears the frame,” Leven points out. Leven says ILM also provided Ben Stiller with options when it came to digitally changing up the look of Lumon’s sterile hallways: sometimes adding extra doors, vents, or even switching door handles. “I think Ben was very excited about having this opportunity,” says Leven. “He had never had a complete, fully computer graphics version of these hallways before. And now he was able to do things that he was never able to do in season one.” (Credit: Apple TV+). 2. Let it Snow (Episode 204: “Woe’s Hollow”) The MDR team – Mark, Helly, Dylan, and Irving – unexpectedly find themselves in the snowy wilderness as part of a two-day Lumon Outdoor Retreat and Team-Building Occurrence, or ORTBO.  Exterior scenes were shot on location at Minnewaska State Park Preserve in New York. Throughout the ORTBO sequence, ILM performed substantial environment enhancements, making trees and landscapes appear far snowier than they were during the shoot. “It’s really nice to get the actors out there in the cold and see their breath,” Leven says. “It just wasn’t snowy during the shoot. Nearly every exterior shot was either replaced or enhanced with snow.” For a shot of Irving standing on a vast frozen lake, for example, virtually every element in the location plate – including an unfrozen lake, mountains, and trees behind actor John Turturro – was swapped out for a CG environment. Wide shots of a steep, rocky wall Irving must scale to reach his co-workers were also completely digital. Eventually, the MDR team discovers a waterfall that marks their arrival at a place called Woe’s Hollow. The location – the state park’s real-life Awosting Falls – also got extensive winter upgrades from ILM, including much more snow covering the ground and trees, an ice-covered pond, and hundreds of icicles clinging to the rocky walls. “To make it fit in the world of Severance, there’s a ton of work that has to happen,” Leven tells ILM.com.

Welcome to Lumon (Episode 202: “Goodbye, Mrs. Selvig” & Episode 203: “Who is Alive?”) The historic Bell Labs office complex, now known as Bell Works in Holmdel Township, New Jersey, stands in as the fictional Lumon Industries headquarters building. Exterior shots often underwent a significant digital metamorphosis, with artists transforming areas of green grass into snow-covered terrain, inserting a CG water tower, and rendering hundreds of 1980s-era cars to fill the parking lot. “We’re always adding cars, we’re always adding snow. We’re changing, subtly, the shape and the layout of the design,” says Leven. “We’re seeing new angles that we’ve never seen before. On the roof of Lumon, for example, the air conditioning units are specifically designed and created with computer graphics.” In real life, the complex is surrounded by dozens of houses, requiring the digital erasure of entire neighborhoods. “All of that is taken out,” Leven explains. “CG trees are put in, and new mountains are put in the background.” Episodes 202 and 203 feature several night scenes shot from outside the building looking in. In one sequence, a camera drone flying outside captured a long tracking shot of Helena Eagan (Helly R.’s Outie) making her way down a glass-enclosed walkway. The building’s atrium can be seen behind her, complete with a massive wall sculpture depicting company founder Kier Eagan. “We had to put the Kier sculpture in with the special lighting,” Leven reveals. “The entire atrium was computer graphics.” Artists completed the shot by adding CG reflections of the snowy parking lot to the side of the highly reflective building. “We have to replace what’s in the reflections because the real reflection is a parking lot with no snow or a parking lot with no cars,” explains Leven. “We’re often replacing all kinds of stuff that you wouldn’t think would need to be replaced.” Another nighttime scene shot from outside the building features Helena in a conference room overlooking the Lumon parking lot, which sits empty except for Mr. Milchick (Tramell Tillman) riding in on his motorcycle. “The top story, where she is standing, was practical,” says Leven, noting the shot was also captured using a drone hovering outside the window. “The second story below her was all computer graphics. Everything other than the building is computer graphics. They did shoot a motorcycle on location, getting as much practical reference as possible, but then it had to be digitally replaced after the fact to make it work with the rest of the shot.” (Credit: Apple TV+). 4. Time in Motion (Episode 207: “Chikhai Bardo”) Episode seven reveals that MDR’s progress is being monitored by four dopplegang-ish observers in a control room one floor below, revealed via a complex move that has the camera traveling downward through a mass of data cables. “They built an oversize cable run, and they shot with small probe lenses. Visual effects helped by blending several plates together,” explains Leven. “It was a collaboration between many different departments, which was really nice. Visual effects helped with stuff that just couldn’t be shot for real. For example, when the camera exits the thin holes of the metal grate at the bottom of the floor, that grate is computer graphics.” The sequence continues with a sweeping motion-control time-lapse shot that travels around the control-room observers in a spiral pattern, a feat pulled off with an ingenious mix of technical innovation and old-school sleight of hand. A previs sequence from The Third Floor laid out the camera move, but because the Bolt arm motion-control rig could only travel on a straight track and cover roughly one-quarter of the required distance, The Garage came up with a way to break the shot into multiple passes. The passes would later be stitched together into one seemingly uninterrupted movement. The symmetrical set design – including the four identical workstations – helped complete the illusion, along with a clever solution that kept the four actors in the correct position relative to the camera. “The camera would basically get to the end of the track,” Leven explains. “Then everybody would switch positions 90 degrees. Everyone would get out of their chairs and move. The camera would go back to one, and it would look like one continuous move around in a circle because the room is perfectly symmetrical, and everything in it is perfectly symmetrical. We were able to move the actors, and it looks like the camera was going all the way around the room.” The final motion-control move switches from time-lapse back to real time as the camera passes by a workstation and reveals Mr. Drummond (Ólafur Darri Ólafsson) and Dr. Mauer (Robby Benson) standing behind it. Leven notes that each pass was completed with just one take. 5. Mark vs. Mark (Episode 210: “Cold Harbor”) The Severance season two finale begins with an increasingly tense conversation between Innie Mark and Outie Mark, as the two personas use a handheld video camera to send recorded messages back and forth. Their encounter takes place at night in a Lumon birthing cabin equipped with a severance threshold that allows Mark S. to become Mark Scout each time he steps outside and onto the balcony. The cabin set was built on a soundstage at York Studios in the Bronx, New York. The balcony section consisted of the snowy floor, two chairs, and a railing, all surrounded by a blue screen background. Everything else was up to ILM to create. “It was nice to have Ben’s trust that we could just do it,” Leven remembers. “He said, ‘Hey, you’re just going to make this look great, right?’ We said, ‘Yeah, no problem.’” Artists filled in the scene with CG water, mountains, and moonlight to match the on-set lighting and of course, more snow. As Mark Scout steps onto the balcony, the camera pulls back to a wide shot, revealing the cabin’s full exterior. “They built a part of the exterior of the set. But everything other than the windows, even the railing, was digitally replaced,” Leven says. “It was nice to have Ben [Stiller’s] trust that we could just do it. He said, ‘Hey, you’re just going to make this look great, right?’ We said, ‘Yeah, no problem.’”Eric Leven Bonus: Marching Band Magic (Episode 210: “Cold Harbor”) Finally, our bonus visual effects shot appears roughly halfway through the season finale. To celebrate Mark S. completing the Cold Harbor file, Mr. Milchick orders up a marching band from Lumon’s Choreography and Merriment department. Band members pour into MDR, but Leven says roughly 15 to 20 shots required adding a few more digital duplicates. “They wanted it to look like MDR was filled with band members. And for several of the shots there were holes in there. It just didn’t feel full enough,” he says. In a shot featuring a God’s-eye view of MDR, band members hold dozens of white cards above their heads, forming a giant illustration of a smiling Mark S. with text that reads “100%.” “For the top shot, we had to find a different stage because the MDR ceiling is only about eight feet tall,” recalls Leven. “And Ben really pushed to have it done practically, which I think was the right call because you’ve already got the band members, you’ve made the costumes, you’ve got the instruments. Let’s find a place to shoot it.” To get the high shot, the production team set up on an empty soundstage, placing signature MDR-green carpet on the floor. A simple foam core mock-up of the team’s desks occupied the center of the frame, with the finished CG versions added later. Even without the restraints of the practical MDR walls and ceiling, the camera could only get enough height to capture about 30 band members in the shot. So the scene was digitally expanded, with artists adding more green carpet, CG walls, and about 50 more band members. “We painted in new band members, extracting what we could from the practical plate,” Leven says. “We moved them around; we added more, just to make it look as full as Ben wanted.” Every single white card in the shot, Leven points out, is completely digital. (Credit: Apple TV+). A Mysterious and Important Collaboration With fans now fiercely debating the many twists and turns of Severance season two, Leven is quick to credit ILM’s two main visual effects collaborators: east side effects and Mango FX INC, as well as ILM studios and artists around the globe, including San Francisco, Vancouver, Singapore, Sydney, and Mumbai. Leven also believes Severance ultimately benefited from a successful creative partnership between ILM and Ben Stiller. “This one clicked so well, and it really made a difference on the show,” Leven says. “I think we both had the same sort of visual shorthand in terms of what we wanted things to look like. One of the things I love about working with Ben is that he’s obviously grounded in reality. He wants to shoot as much stuff real as possible, but then sometimes there’s a shot that will either come to him late or he just knows is impractical to shoot. And he knows that ILM can deliver it.” — Clayton Sandell is a Star Wars author and enthusiast, TV storyteller, and a longtime fan of the creative people who keep Industrial Light & Magic and Skywalker Sound on the leading edge of visual effects and sound design.

Where others have become obsessed with speed and trends, Sergio Membrillas has built a career on slowing down and staying true to his craft. Over 13 years as a professional illustrator, he's evolved a distinct style – bold, graphic, and quietly playful – that feels both timeless and entirely his own. But this evolution, as he's quick to point out, wasn't something he forced. "I believe evolution is essential for every artist," Sergio reflects. "Change is not something I resist; it's something I enjoy and welcome as part of the creative journey." His work, initially influenced by a love of Mid-Century graphic design, has gradually absorbed references as diverse as Etruscan art, Mesopotamian motifs, and early 20th-century traditional tattoos. It's a portfolio built on curiosity, not conformity. Despite his stylistic clarity, Sergio's process remains refreshingly analogue at its core. He still begins each project with pencil and paper, leaning into the tactility of drawing by hand. "I've always valued having a physical relationship with art," he says. "There's something essential about feeling the wood of the pencil, manually erasing mistakes, rather than simply double-tapping a screen." His philosophy of working slowly, attentively, and with purpose shows in the balanced compositions and confident use of negative space that has become his signature. Sergio credits his background in graphic design for this instinctive sense of structure. "There has always been a strong graphic sensibility within me," he says, noting that the discipline of design continues to inform his illustration practice, particularly in editorial and poster work where clarity and storytelling must co-exist. Yet, like many creative careers, his path into illustration wasn't plotted from the start. Initially, Sergio imagined illustration would complement his design projects, not become the main event. "At first, I thought I would incorporate my illustrations into my graphic design projects – but in the end, it turned out to be the other way around." A commission for EasyJet's in-flight magazine marked a pivotal moment that reframed illustration from a hobby to a profession. "It made me realize that being an illustrator is a real profession, just like any other." Fast-forward to today, and Sergio's client list reads like a who's who of publishing and design, from The New Yorker to Pentagram. While the calibre of collaborators has changed, what matters most remains the same: trust. "When a client trusts your work and approaches projects with an open mind, collaboration flourishes," he says. It's in these open, trusting relationships that Sergio finds the space to experiment and further develop his ideas. Unsurprisingly, editorial work holds a special place for him. "Editorial projects offer wider creative margins, allowing for greater flexibility and innovation," he explains. Compared to the tighter confines of advertising, editorial illustration offers the opportunity to tell nuanced stories, and Sergio is clear that he views every assignment, regardless of format, as a collaborative effort. If one thing is clear, though, it's that he's not that he's afraid to say no when needed. Maintaining a strong personal voice is non-negotiable. "I always strive to stay true to myself and ensure that every project I undertake reflects a clear personal signature," he says. For Sergio, authenticity isn't just a matter of artistic pride; it's what differentiates an illustrator in a saturated, increasingly automated industry. Valencia is home for Sergio, a city he credits with much of his creative energy. "Oh, Valencia! It's a beautiful city that inspires me and brings me joy," he says, describing it as a European cousin to Los Angeles with its sun-soaked streets and vibrant cultural scene. The blend of tradition and modernity fuels his practice, offering constant inspiration without the sensory overload that often accompanies larger creative hubs. Given the pressure many creatives feel to keep pace with shifting trends, Sergio's approach feels almost radical. "I'm not particularly interested in trends," he says. "What truly matters to me is the feeling of having done something meaningful and fulfilling by the end of the day." Instead of chasing what's fashionable, he draws inspiration from a surprisingly eclectic bookshelf, mixing everything from Wim Crouwel's graphic design classics to studies on Scandinavian tattoos and Alec Soth's photography. It's a reminder that fresh ideas rarely come from looking where everyone else is looking. In the era of AI and content overload, the role of the illustrator is changing, but Sergio remains optimistic. While machine learning might churn out images at record speed, it can't replicate the nuance and emotional intelligence that underpin great illustration. "Illustrators can tell stories, evoke emotions, and create meaningful connections that machines simply cannot replicate," he says. "Our role is shifting, but the value of authentic, thoughtful illustration remains indispensable." That insistence on authenticity carries through to the advice he offers younger illustrators navigating a commercial landscape. "Create work that makes you happy when you go to sleep at night," Sergio advises. "It's important to find projects that align with your values and passions so your artistic voice remains authentic." It's an ethos that has carried him through more than a decade of creative highs and industry shifts. Perhaps it's the real secret behind the clarity of his practice, which he has built not on chasing trends or algorithms but on careful craft, deliberate evolution, and the simple, enduring joy of a well-made pencil and a blank piece of paper.

Credit: University of Hawai'i Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. At any given time across the universe, massive cosmic bodies are releasing incomprehensible amounts of energy. Stars burn like celestial nuclear fusion reactors, quasars emit thousands of times the luminosity of the Milky Way galaxy, and asteroids slam into planets. But all of these pale in comparison to a new class of events discovered by researchers at the University of Hawai’i’s Institute for Astronomy (IfA). According to their findings published June 4 in the journal Science Advances, it’s time to classify the universe’s most energetic explosions as extreme nuclear transients–or ENTs. ENTs are as devastating as they are rare. They only occur when a massive star at least three times heavier than the sun drifts too close to a supermassive black hole. The colliding forces subsequently obliterate the star, sending out plumes of energy across huge swaths of space. Similar events known as tidal disruption events (TDEs) are known to occur on a (comparatively) smaller scale, and have been documented for over a decade. But ENTs are something else entirely. “ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions.” Hinkle was first tipped off to ENTs while looking into transients—longlasting flares that spew energy from a galaxy’s center. Two particularly strange examples captured by the European Space Agency’s Gaia mission caught his eye. The pair of events brightened over a much longer timeframe than previously documented transients, but lacked some of their usual characteristics. “Gaia doesn’t tell you what a transient is, just that something changed in brightness,” Hinkle said. “But when I saw these smooth, long-lived flares from the centers of distant galaxies, I knew we were looking at something unusual.” Hinkle soon reached out to observatory teams around the world for what would become a multiyear project to understand these anomalies. In the process, a third suspect was detected by the Zwicky Transient Facility at the Palomar Observatory in San Diego. After months of analysis, Hinkle and collaborators realized they were witnessing something unprecedented. An infrared echo tells us that a dusty torus surrounds the central black hole and newly-formed accretion disk. Credit: University of Hawai’i The ENTs analyzed by astronomers displayed smoother, longer lasting flares that pointed towards something very particular—a supermassive black hole accreting a giant, wayward star. This contrasts with a more standard black hole that typically acquires its material and energy unpredictably, resulting in irregular brightness fluctuations. The energy and luminosity of an ENT boggles the mind. The most powerful ENT documented in Hinkle’s study, Gaia18cdj, generated 25 times more energy than the most powerful known supernovae. For reference, a standard supernova puts out as much energy in a single year as the sun does across its entire 10 billion year lifespan. Gaia18cdj, meanwhile, manages to give off 100 suns’ worth of energy over just 12 months. The implications of ENTs and their massive energy surges go far beyond their impressive energy outputs. Astronomers believe they contribute to some of the most pivotal events in the cosmos. “These ENTs don’t just mark the dramatic end of a massive star’s life. They illuminate the processes responsible for growing the largest black holes in the universe,” said Hinkle. From here on Earth, ENTs can also help researchers as they continue studying massive, distant black holes. “Because they’re so bright, we can see them across vast cosmic distances—and in astronomy, looking far away means looking back in time,” explained study co-author and astronomer Benjamin Shappee. “By observing these prolonged flares, we gain insights into black hole growth when the universe was half its current age… forming stars and feeding their supermassive black holes 10 times more vigorously than they do today.” There’s a catch for astronomers, however. While supernovae are relatively well-documented, ENTs are estimated to occur at least 10 million times less often. This means that further study requires consistent monitoring of the cosmos backed by the support of international governments, astronomical associations, and the public.
