Heart

In Heart a woman is hurled against a wall after every 500 beats of her
heart by means of a cable attached to her body. Her heartbeats are
audible to the spectators. Because of the stress situation the woman is
in, it is of course impossible for her to control her heartbeats: she
cannot but surrender to the machine of her own heart, to the
unpredictable, sublime moment when the cable is tugged and she is
thrown against the wall, again and again.
