“California Dreamin”
The sculpture consists of 3 different tracks which a ball bearing follows, the route of the ball is changed automagically thanks to “gravity operated, magnetically optimized, switching units” (metal lever things).
“Cheborgie #1”
“Cheborgie #1” (79x33x27) is a kinetic art musical rolling ball sculpture which has a steel ball that starts at the top and by gravity follows a rollercoaster track, does jumps, goes down stairs, through chimes, past a spinner, and through a tube.
“Cheborgie #2”
“Cheborgie #2” (80x36x37) is a kinetic art musical sculpture which has a steel ball that starts at the top, and by gravity follows a rollercoaster track, does a loop, switches directions, goes through three chimes, around a spiral, and through a spring tunnel.
“Soundgarden”
“Soundgarden” (53x46x11) is a kinetic wall sculpture with a steel ball that starts at the top track, and by gravity follows a path over a variety of musical tracks and chimes. Everyone smiles when they see this one in action. You must see and hear this one to appreciate it.
