This is a very tabletop-friendly RBS. It’s wide but not very deep, so it can sit comfortably on a table against a wall without taking up a lot of space.

There are three tracks. The first is a loop d’ loop with 10 inversions that ends in a line of stationary balls—an element I call “balls on track.” Ten inversions is about the limit of what I can build with my 12-foot pieces of stainless steel rod. The next fast track is a tall, skinny coil.

The long track takes its time getting to the bottom, with a ball-collecting tipping arm, a regular tipping arm, horizontal zig-zag, flat spiral, wavy track, and lots of back-and-forth movement filling the sculpture.

All three tracks eventually merge into one and the balls line up at the bottom for another trip up the chain lift.
