Bluetooth soccer ball brings the noise
Musician and inventor Aleksei R. Stevens has created a concept product called the SoundBall. The SoundBall is a soccer ball that is filled with motion sensors that detect when the ball is being rolled, dropped, kicked, or spun. The motion data is then transmitted over Bluetooth to a local computer that bleeps out corresponding electronic noises.
My guess is that he's got some kind of Arduino or Parallax board inside the ball and Cycling '74 Max/MSP music software running on his computer. Whatever he's using, it looks like a fun way to kill some time and annoy the neighbors. I can't wait until someone comes up with a cat toy version!

This is Aleksei, the creator of the soundball. Unfortunately, my registration of the site you're linking to here lapsed, and it was bought up by a Russian guy who put up some pretty offensive filth. I wouldn't want you driving any traffic there, and I wouldn't want your readers to accidentally wind up looking at it. Please update all your links to go to my new site, www.alekseistevens.com.
Many thanks,
Aleksei
