Heart Beats Dust – Cone Pyramid, 1968
In a black rectangular box, a window at eye level opens onto a 24′ cube which houses the sculpture. The form is created by thrusting dust up into a cone of light. The dust is Lithol Rubine, a brilliant red pigment chosen for its ability to remain suspended in air for long periods. The thrust is achieved by amplified heart-beats from an attached stethoscope or a continuous loop tape recording of heartbeats played on a speaker mounted directly under a tightly stretched rubber membrane upon which the dust sits.
