Chladni Resonance
Sand patterns forming on a vibrating plate, morphing between harmonic modes with golden glow.
What is Chladni Resonance?
Chladni Resonance is a free WebGL web effect in the TappyPrism library. Sand patterns forming on a vibrating plate, morphing between harmonic modes with golden glow. It is rendered on the GPU by a fragment shader, so it costs almost nothing on the CPU and works well as a full-screen background. It ships as a single self-contained HTML file (chladni-resonance.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Mode Speed, Complexity — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Mode Speed | MODE_SPEED | 0.1 – 2 | 0.5 |
| Complexity | COMPLEXITY | 2 – 8 | 5 |
