This kinetic sculpture is a ball bearing’s paradise. Not only do they get a cushy ride around two lift wheels but there’s a variety of enjoyable obstacles they can go down. The first is a vortex made from a wooden flower pot which sends the balls randomly down one of two possible exits. From there it’s on to enjoy a ride on a flip-flop, a divide-by-three (takes weight of three marbles before it dumps them all), a zig-zag track, or a divide by twelve mechanism. We’re sure this is a riveting read, but don’t miss the video after the break where [Ronald Walter] shows it in action and takes it apart to illustrate the various features.
If you’re wondering about the digital logic terms used, we’ve seen wooden devices that use these concepts in the past.
