SoundBall is a ball with sensors that make it emit sounds according to what it’s movement is. The ball transmits what it’s doing via Bluetooth, enabling it to control music and sound through motion.
It’s creator, Aleksei Stevens, calls it a toy. But I reckon if you put it onto a field for blind soccer players you’d have an improved experience over the static bell currently used. The sounds of what the ball is doing, in addition to where it actually is, could offer the players more feedback.
Maybe something similar, on a smaller scale, could be used for the game of Swish too.

Hi there,
Unfortunately, I accidentally allowed my registration of the site you’re linking to here to lapse, and it was bought by someone else who has posted some really offensive filth to it.
Please change all links to direct to my new site: http://www.alekseistevens.com.
The video, which contained a link to the old site, had to come down as well. I’ll let you know when I get a new one up.
Thanks,
Aleksei Stevens
