Another video of details.
This is a Rolling Ball Sculpture. The balls roll down tracks, and different things happen to them. A ball roll in front of the wizard, stops, and the track drops away as the ball floats in the air by magnetic levitation. When it is done, it flies out to the right to another track.
Another ball rolls onto a magic carpet, which then carries the ball up.
A ball lands in a small cart pulled by a hand-pumped railroad car to the other side.
After four balls get lined up on the upper left, they are released to go down a track, shooting off the track where they bounce off a pad, go up into the air, and land in a funnel.
The Wobble Lift hands balls from one little “hand” to another to carry them up.
