[Mojo Jojo] mentioned this link in yesterday’s comments. It’s really simple and the author has expanded the description since it was featured on Slashdot. The hack describes how to wire sets of red, green, and blue LEDs with the goal of producing all possible colors. Definitely a cool effect with minimal effort, a good starter project. Not sure if kits are still being sold, but they should save you some money on parts. Can someone come up with an adaptive color controller for this?
