Hokey Spokes - Bicycle Safety Lights with LED spoke lights for your bike
When I was back getting my BSEE, I built a circuit for my Digital Logic class that exploited this fun concept.....that a quickly moving row of LEDs + persistence of vision can make for lots of fun! This guy took it one step further and mounted them on bicycle wheels -- there are numerous patterns to cycle through, a customizable text message, even a way to program them from your Palm.
