This tutorial uses a "random speed falling LED array of lights" example to teach the use of generating a band, adding a glass effect to the cylinder, animating the LED band, and randomizing the speed for each LED tube. These concepts can be used to make a wide variety of useful materials to meet your aesthetic needs. Enjoy!
