Cybernetic objects are self-regulating or recursively acting systems that seem to act independently. In the Sculpture installation, the computer initially generates manually generated sounds, which are measured by a microphone in their volume and trigger new sounds at the appropriate volume. This system acts completely self-sufficiently and creates different sound patterns as well as visual objects in the form of short video passages. During the performance, the composer does not interfere with the way it works, but merely changes the sounds or video scenes used.
