This sculpture takes the oloid in another direction. Attaching an ellipse and a circle at an angle other than 90° results in a form that rolls back and forth like a pendulum.

These process shots show multiple iterations and experiments explored to find the optimal boomerang-like motion. The more disparate the centers of gravity between the circle and the ellipse depends on the acuteness of the angle of attachment. The object oscillates as it seeks equilibrium. Crafted in both steel and wood, for more information see parachute.
