Ladyada writes about her Pac-Man wheels – “The technology here is “persistence of vision”…when LEDs move fast enough they can “draw” an image when the wheel spins. That’s the basis behind both the MiniPOV and SpokePOV toys that I designed last year. I rode this design around last burningman, obviously ive adjusted the image so they’re “upside down” here for better photographing! If you’d like to build your own, check out the full instructions on Instructables – Link.
