MIT graduates James Patten and Ben Recht designed the Audiopad, an interactive tabletop system which tracks the position of objects and converts their motion into music. For those who haven't already seen the Audiopad, video demonstration after the jump. It's an oldie but goodie.
Audiopad has a matrix of antenna elements which track the positions of electronically tagged objects on a tabletop surface. Software translates the position information into music and graphical feedback on the tabletop. Each object represents either a musical track or a microphone.
