Songdeck vs Cymatics Lab

This app is only for people who have purchased our physical song card deck. Draw a card from the deck and scan the QR code to play a song for joy, regulation & transformation!

Watch thousands of sand particles arrange themselves into geometric patterns in real time, driven entirely by the physics of sound. Cymatics Lab simulates a vibrating plate with accurate physics. Drop particles, play music or speak into your mic, and watch the sand migrate to the stillest points on the surface, forming intricate, shifting geometric shapes. The same science that fascinated Chladni in the 1700s, now running on your phone. 5 WAYS TO SEE SOUND Square — The classic Chladni plate. Rectangular nodal patterns shift and evolve with your sound. Circle — Circular plate with Bessel function eigenmodes. Concentric rings bloom outward like a cymbal frozen in slow motion. Cavity — A 3D resonant chamber. Sand moves through depth, not just across a flat surface. Lissajous — Orbital particle paths inspired by Lissajous figures. Hypnotic, looping geometry. Quasicrystal — Patterns that repeat forever but never tile. Five-fold and higher symmetries in motion. ANYTHING CAN BE A SOUND SOURCE Mic Input — Speak, sing, clap, play an instrument. The sand responds instantly. Apple Music & Spotify — Connect your streaming library and visualize your favorite tracks. Music Library — Play songs stored on your device. Frequency Engine — Dial in exact Hz values and watch the sand snap into resonance. Stack harmonics. Sweep through ranges. MAKE IT YOURS Main Panel — Control sand count, particle size, force sensitivity, and bloom. Physics Panel — Adjust vibration modes, resonance sharpness, frequency multiplier, sand collisions, and experimental effects. View Panel — Orbit the camera freely. Choose skybox environments, room lighting, and plate appearance. Art Panel — Layer on symmetry reflections, energy glow, particle trails, bloom, and color palettes. Studio Panel — Save and load presets. Enable beat-reactive effects that sync to the music: bloom pulses, gravity shifts, burst explosions, sweep waves, color cycling, depth warping, shimmer, ripple, and dissolve.

WHO IS THIS FOR? — Everyone. Browse the Waves community and get lost in patterns others have created, Just scroll and enjoy with your own sounds or music. — Musicians and visual artists who've always felt their sound was something to be seen. Connect your music and watch it take shape. — The curious who want to watch physics happen in real time. Change one setting and see how sound behaves differently. — Educators teaching acoustics, resonance, and wave phenomena. A living, interactive demonstration. — DJs and performers who want a live visual companion on stage or on screen. Cymatics Lab is built by a single developer who cares about the science as much as the art. No ads. No subscriptions. Just sound made visible. See what your music has always looked like.
