My electronic sculptures and reliefs react to the spectator by means of photocells or microphones. The observer with his gesture or movement can throw shadows upon the light sensitive cells or can talk to them, the object then reacts within the bounds of its possibilities which are sound, movement or light. The subject of my work is the presentation of time structures which includes interactive and musical structures. The logic electronic function of these sculptures is determined, but the reactions sometimes seem random because of the sensitive dependence upon the time pattern of the input (the activities of the spectator).
