Cymatics Simulator V2

The first simulator was film of the real dish. This one is the dish, in code: a circular dish of water driven from below carries standing waves whose wavelength the water decides and whose shape the dish decides, lit by a ring of LEDs and seen as the camera sees it — the ring's reflection, caught wherever the water tilts just so. Dial the frequency, resize the dish, change the light. Turn the sound on to hear the tone that drives it.
