[Alex Hornstein] was bored one Saturday and decided to do something with the large pieces of scrap acrylic he had found. He built a cube and attached 15 RGB LED clusters along with 4 GB LED sticks. It takes 50W of power. The controller is built from ATmega48 and is controlled via serial commands over a wireless link from Spark Fun. You can find schematics, pictures, and video on his site, Art is Wrong.
