Cymatic

A tone generator that paints its own sound in sand
by jake

Cymatic is a live Chladni plate simulator: play any frequency and watch the exact standing-wave pattern it produces emerge in real sand, in real time. Pick a musical note or drag the frequency slider and simulated grains drift down the vibration field until they settle along the silent nodal lines, tracing the actual physics of cymatics (the study of visible sound). Dial in the plate's vibration mode numbers directly for the full range of Chladni figures, tap the plate to excite it and watch the pattern ripple and resettle, and save or share any pattern you land on. A hands-on physics demo and a generative sound-to-pattern art tool in one — for anyone searching for a Chladni plate simulator, a sound wave pattern generator, or a way to actually see what a frequency looks like.
