A "threedimensional" sound experience is waiting for visitors to the exhibition "Knowledge ". The movement of the robot flock determines the acoustics in the room. Pockets of sound form on the ceiling and wander throughout the room, changing their direction, speed and volume as they do so. Single "threads" of sound are pulled by acoustic ripples or spun into tonal whirlpools.
Microphones that pick up the background noise are also placed throughout the entire hall. The sounds are transformed and broadcast back into the hall. The robots themselves also generate sounds which change with every new film on their surfaces.
