Cool Hunting: Laughing Bike

This is a cool idea. I have also heard that someone from Holland has invented an ipod recharger based upon biking...

Cool Hunting: Laughing Bike: "Another highlight from the Basel weekend (yes, updates are still coming) was Soundbike, an art project by Jessica Thompson. Basically, a fleet of bikes was outfitted to emit laughter when the rider pedals. The faster the pedaling, the louder and more hysterical the laughter. In addition to being a lot of fun, I though her piece was a perfect little statement on the art consumption frenzy that was Art Basel."
