Imagine yourself on a sunny day, biking through the beautiful countryside. In one of those shots that could come straight from some 70s film, the sun arcs behind you and the wildflowers and trees bend lightly in the breeze. The sound of laughter (your own) trailing behind in your wake. It's a far cry from the typical grunts and shouts of those lycra-clad distance cyclists who often clog the park, or the lean mean (and ever decreasing in number) bike messengers who zip through city streets. The Soundbike, a project by Jessica Thompson, seems to be trying to interject some lighthearted fun back into urban cycling. The project, at the core, is just a regular old bike, but what makes it special are the motion sensors that respond to the velocity of the bicycle which trigger audio samples of laughter. The end result? A thrilling ride that brings giggles everywhere you go. Imagine a fleet of these touring around Central Park or flying through Times Square with Critical Mass. It would be a nice pick-me-up for all the grumpy pedestrians and tourists.
