While the Pac-Man themed version of this mobile LED light show is pretty genius, the programmable kit allows for any number of other clever combos or other bitmapped images for animated self-expression on wheels. Adding safety to boot, the DIY project is not for the tech-challenged, requiring basic programming and soldering skills to create the custom images for either regular size or smaller wheels.
