Jean Dupuy-Cone Pyramid

I just found this in a book, "Formless", the artist uses the vibration of the hearbeat as a pulse to trigger the red pigment dust particels to fly inside the box with a light attatched at the bottom. The exactaly the same technology I used in my dust house, but he done it in 1968, and with an interesting narrative as base, what am I doing then? the out come of dust pattern for what?

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.
