PENDULUM DEVICE 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 position from which the pendulum is released and the depth of penetration of the tip of the scribe. A pair of low friction, point bearings define a primary, horizontal axis of swinging movement of the pendulum, and the intricacy of the patterns is enhanced by a resilient, upright standard that sways with the directional pull of the pendulum. The elevation of the pendulum is controllable in order to set the depth of penetration of the scribe and thereby control the depth and width of the lines of the patterns. In a modified embodiment, the weight of the pendulum may also be varied in accordance with the pattern configuration desired.
