Rolling-Ball Sculpture

What it is

A desk-sized kinetic sculpture in polished metal: a wheel with eight cradles lifts chrome balls one by one and tips each onto a pair of rails at the top; the balls roll down a spiral round a column and back across the front of the base into the wheel again, speeding up where the track is steep and easing off on the gentle stretches, while the rails cast thin shadows on the wood. Choose the metal (brass, copper, steel or black), the base (walnut, oak or black), the number of balls and the backdrop.

Reuse it in your own idea

• Process explainer: Brass on walnut behind a title about how your pipeline works.
• Satisfying loop: Steel on black with 16 balls, camera drift on, for a full-screen loop.
• In your own scene: add the group to a desk scene and call update(seconds).

Which part is reusable

src/rolling-ball-sculpture.js is the ingredient your AI reuses. demo.js is only the example scene around it, and uses chrome-material only for the demo.

Good to know

• The balls follow the track by design rather than a physics simulation: they never collide or jump.
• The track layout is fixed; the parameters change its materials and the number of balls.
