“Marionette” is an interactive video installation. In a dark room three differently large timber panels hang one above the other, on which head, torso and legs of the marionette are projected in each case.Each part of the body is a film of its own. By means of a program the fragments are compiled to a coherent body. In front of the projection stands a microphone, which is attached to a computer. The visitor controls the movement of the marionette by using the microphone. This happens for each of the three body sections separately, because the parts of the body react to different frequency domains. While the head reacts rather to higher frequencies, the legs of the marionette move themselves to lower frequencies and the torso to center frequencies.
