This is a series of works based on circular causality: A influences B which influences A and so on. One of  these works is simply achieved by providing two chairs and two stetoscopes to the public (two at a time). The two people will be both performers and spectators, each one will be listening to the others' heartbeat through the stetoscope.
A variation (only theoretical for now) consists in placing a cam over a pair of VR glasses, repeating this process and then connecting each cam to the opposite VR glasses. Two people should wear the glasses and the result is a performance and composit video.
