is a sound sculpture. Two tubular constructions are
placed on turntables. Shadows of the two rotating objects are
projected onto a transparent screen in the front.
Microphones inside the tubes are in audio feedback
constellation with two loudspeakers scanning the sonic
environment like a radar.
This way the movement of the turntables is directly related to
the sound produced. The speed of rotation changes arbitrarily
and turns the sound into an random composition.
People moving around the sculpture influence the acoustic
character of the work.
