iPod racer

I got this idea from the star-wars "Pod-racing", but just the name. The concept is to produce toy cars that carries iPods, and uses iPod power as power source. The most interesting part is it uses the audio signal streamed from the iPod to control its speed.

So say you and your friend both possess an ipod. plug your ipod into the racer, and select an appropriate song to play. Your choice of song would determine the speed and the rythm the racer runs. While ballads or new age makes your racer cruise, techno will cause your racer to run in short and fast bursts. Now each of you can pick your favorite song, and race your music for a bet.

Fun?
