Sand, sound & standing waves

Sand. Sound. Standing waves.
Cymatic is a pocket Chladni plate — the centuries-old physics demo where sand on a vibrating metal plate flees the shaking regions and gathers along invisible "still" lines, drawing eerily symmetric figures.
Everything you see is around 9,000 grains of simulated sand reacting to a vibrating surface in real time. Nobody draws the lines — the grains find them on their own. It's part science, part meditation, endlessly mesmerizing.
WHAT YOU CAN DO
• Tap the plate to retune it and watch the sand stampede into a brand-new figure.
• Long-press for a clean, full-screen, controls-hidden view.
• Dial the pattern numbers to summon a specific figure.
• Push the plate harder or softer — razor-sharp lines or shimmering, breathing ones.
• Turn on sound to hear the exact tone that produces what you're seeing.
REAL PHYSICS, LIVE
Cymatic doesn't fake these patterns. Each grain is kicked harder where the plate shakes more, so the swarm settles onto the calm nodal lines — an emergent picture of a standing wave you can't otherwise see. Every pattern even gets its own color signature.
CALM BY DESIGN
No timers, no scores, no streaks. Just a quiet, beautiful object to fidget with, show a friend, or stare at while your mind wanders.
PRIVATE BY DEFAULT
We do not collect any data. No analytics, no tracking, no accounts, and no network — every grain is computed on your device, and nothing you do ever leaves your phone.
Free. No ads. No in-app purchases.
