The Audiopad is a musical composition and performance instrument which tracks the positions of objects on a tabletop surface and converts their motion
into music. The system, which is powered by Debian Linux, combines a set of electronically tagged objects on a tabletop surface, a matrix of antenna
elements to track the objects, and an LCD projector to display an animated user interface.
