The Solar version pulse-moves the elegant hand-off mechanism that passes marbles to the top of a sweeping multi-level track. You will witness the fascinating step-by-step action of the arms as the geometry changes periodically.


Patience is rewarded with the plunk, and roll of a successful motion cycle. The more light it gets, the more often it moves. It's solar-powered stop-action motion!
