This desktop rolling ball sculpture has a beautifully balanced shape, with the tracks sweeping around the frame as the marbles make their way from top to bottom. It’s compact, portable, and designed to be enjoyed from just about anywhere.

The semi-automatic ball release makes it especially fun to watch. Fill the queue at the top and release the first marble. When it reaches the bottom, it presses a lever that releases the next ball. The process continues on its own until the queue is empty.

It’s the best of both worlds: automatic action without a motor, batteries, or electricity. Gravity and the movement of the marbles do all the work.

Because there’s no power supply or motor to deal with, the sculpture can easily be picked up and moved wherever you want a little kinetic entertainment.

Handmade from 100% stainless steel and TIG welded. You could practically put the thing in the dishwasher to clean it.
