Perich's Microtonal Wall

Tristan Perich's Microtonal Wall consists of 1500 small speakers arranged in a grid and mounted on to a 25 foot long panel.  Each of these small speakers emits a single different 1-bit tone, which becomes a voice in a sonic mass that shifts and transforms in relationship to the listener's position in the room.
