ABSTRACT:
A dynamic artwork having a pendulum support and a plurality of pendulums positioned side-by-side on the pendulum support wherein each pendulum comprises a plurality of spaced apart end members and an interconnecting central structure which includes a hub. The hubs mount on the pendulum support such that the pendulums have pivotal movement about a horizontal axis. The end members of each pendulum have sufficient mass to provide inertia power for a plurality of swings of each pendulum in response to a starting force applied to the pendulum. Each pendulum swings back and forth about its horizontal axes, within a vertical plane, adjacent each other pendulum until the motion is damped out.
