While I’ve built quite a few manually operated rolling ball sculptures, I’ve rarely made them to hang on a wall. This one puts the viewer in control.

Place the marbles in the queue at the top, where they wait until you press the handle to release them. Send one, two, or all of them at once onto four different tracks, then watch each take its own route through the sculpture.

One track drops through a vertical zig-zag on the left. Another dives through a loop d’ loop cutting across the center. A tall, skinny coil sends its marble out at high speed and into a “balls on track” element. The longest route winds through wavy track, a tipping arm, and several tight hairpin turns as it weaves in and out of the other elements.

There’s no motor and no automatic lift—the interaction is part of the sculpture. Pick up the marbles, load the queue, pull the handle, and do it all over again.
