SOLD!! 

This wall mounted rolling ball sculpture is 32" wide X 24" high X 10" deep. There are 1" colorful glass marbles rolling around on the three different tracks. 100% stainless steel construction. 

There are several different elements to watch on this busy sculpture. Two track splitters send the marbles on their way through a teeter totter catch-and-release mechanism, tipping arm, loop d' loop,  marble collector, and an automatic flat plate that tips up and down sending the marbles rolling back and forth.  Very mesmerizing to watch! 

All of the marble action merges back into one track while returning to the automatic ball lift - and another run down the stainless steel tracks. 
The motor has 6 speed settings - and if you run it at top speed, all of the marbles get trapped in the automatic tipping steel plate because it doesn't tip long enough for the marbles to escape haha.
