Laserpointerforums member FireMyLaser built this most excellent Spinning RGB LED Ball II, using a bit of junk from his scrap pile and lots of ingenuity. He mentions that it uses a total of nine slip ring contacts, which is no mean feat considering that the whole thing was made by hand and spins at quite a fast speed. [Thanks, Matt!]
