The Swing Sticks Sculpture shouldn’t need any introduction. It made an appearance in Iron Man 2 and has been covered online a lot. The desktop version is great but the full size version is larger and much more impressive. It has aluminum sticks that revolve in seemingly perpetual motion. Of course you need 4 batteries to keep this going.
The Swinging Sticks sculpture is designed in Germany and hand assembled. It remains in motion unassisted. This piece measures 16 1/8″ x 3 3/4″ x 17 1/2″.
