Cascade
Steer a waterfall of physics particles onto a row of tuned bars — a browser marble machine you compose by aiming the flow.
Particles fall under gravity from the emitter at the top. Tilt the angled deflectors to divert the stream onto nine tuned bars — grab a deflector’s middle to move it, an end to rotate. Aim for a groove; over-drive the emitter and it turns to a wash.
