ABSTRACT OF THE DISCLOSURE In a kinetic sculpture apparatus, the lower end of a pendulum provides a scribe having a tapered tip that penetrates the surface of a bed of fine, particulate material to make an intricate pattern in the bed whose configuration is determined by the location of the pendulum's primary horizontal axis, the position from which the pendulum is released, and the depth of penetration of the tip of the scribe. The suspension system for the pendulum includes an arch which spans a pair of standards disposed on opposite sides of the receiver that contains the bed of material, in order to maintain the primary axis of the pendulum at the same elevation as the pendulum swings to thereby assure that the depth of penetra- tion will be uniform. The pendulum assembly is mounted above a baseplate by a ball and socket connec- tion which permits the entire assembly to be tilted in any direction to move the at-rest point of contact of the scribe away from the center of the bed to any quadrant or region thereof where a subpattern is to be sculptured. Additionally, the receiver is inde- pendently rotatable about a vertical (or slightly inclined) axis through a selected angular displace- ment to permit the sculpturing of angularly spaced repeat patterns. A highly stable suspension is pro- vided by a disc-shaped rocker element having a central slot therein through which the arch extends, the arch (Docket 384) having a V-shaped portion receiving the element in an upright attitude to define the primary axis of the pendulum. Bed shaping is provided by a dish-shaped cover for the receiver having a con- vex lower surface.
