A marble-run workshop with ramps, funnels, spinners, and a satisfying drop.

Starts when you do.
Choose a tool and build a path. Drop a marble, or turn on Rain to test the whole run.
Best with a little space. For detailed controls on a phone, turn to landscape. Leaving the experiment stops its motion and audio; restarting begins a fresh session.
