Andrew Fentem has a video on his site of a very cool interactive LED cube. He doesn’t post any information about how the cube is made, but here is his ‘artist statement’:
World’s first cubic touchscreen computer games platform
(2007)
Featuring a unique ultra-bright (even in daylight) full-colour cubic screen and a unique cubic multitouch touchscreen technology (patent pending) this games platform has been programmed to implement various multi-dimensional games, puzzles, and lighting effects. This object will shortly be for sale in a limited edition from Kinetica Museum, the UK’s electronic art museum.
