Record for YouTube
The video frame on the stage is exactly what gets recorded, with sound. The controls and note readout are left out. Keep this tab in front while recording, since browsers slow down hidden tabs.

How it works
Each note is tied to one vibration mode of an idealized square plate, written (m, n). Low notes get simple modes and high notes busier ones, the way real plates behave.
The bright lines mark where sand would gather, at the places that stay still. The colored panes between them are the parts that move. Their slow pulsing is the standing wave's back-and-forth, slowed from hundreds of cycles a second to a few seconds.
Choose the Plate resonances scale to hear each mode at its true relative pitch, proportional to m² + n². With several notes at once, real sand would blur into dots, so here each voice draws its own lines in its own color.
