Here is another marble run that puts on a mesmerizing show as the balls roll down its tracks. The Ten Rolling Ball Sculpture is made with stainless steel and TIG. When you turn on the sculpture, it scoops up the marble, takes it to the top, and releases it. On its way down, the marble triggers a mechanism that turns the number wheel up one digit at a time.
This rolling ball sculpture has a light on top. It runs on a 12v adapter. You can find this piece on Etsy. More information is available here.
