Ah, yet another clever persistence of vision project. I think this is my favorite so far because of its interactive nature.

All of the display and processing components are mounted to the rotating arm. The gamepad signal is transfered through ball bearings mounted on the shaft. He’s got it to play Tetris and Pong, display a clock and text from the serial port. It would be interesting to see a game that took advantage of the full 360 degree display; maybe an infinite side scroller.
