Spoke POV is an easy-to-make electronic kit toy that turns your bicycle wheel into a customized display! The project includes a free schematic design, open software for uploading and editing stored bitmap images, and a high-quality kit with all the parts necessary to build your own.
Lady Ada is selling the kit from her site for a mere $37.50 and she has a couple of other POV projects that are even cheaper. How long do you think it’ll be before some toy maker nabs this idea for a commercial product for kid’s bikes?
Man, now I want to go out and buy a bicycle just so I can have a couple of these on it as I ride around.
