This free standing sculpture was sold through "Coolest Toys on Earth" in Milford, OH. They have a website, check them out!
But, what you want to know about is the sculpture. It is 4ft tall X 4ft wide with three different tracks. Track one is a loop d' loop which 6 loops, and ends with the ball stopping itself with its own back-spin. Track two has a marble collector which tips when the 3rd marble rolls onto the collector. The third track has just a single marble which speeds around the sculpture. There is a chain lift that raises the marbles back to the top. The marbles are 1-3/8" colorful glass marbles. Be sure to see the video at the bottom of the page to see it in motion.
