Moiré Interference
Overlapping concentric ring patterns creating hypnotic emergent moiré interference in blue-violet and teal.
What is Moiré Interference?
Moiré Interference is a free WebGL web effect in the TappyPrism library. Overlapping concentric ring patterns creating hypnotic emergent moiré interference in blue-violet and teal. 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 (moire-interference.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Ring Density, Drift Speed — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Ring Density | RING_DENSITY | 0.3 – 2 | 1 |
| Drift Speed | DRIFT_SPEED | 0.1 – 1.5 | 0.5 |
How to add Moiré Interference to your page
- Download the standalone file moire-interference.html and copy its source into your project.
- Or embed it as a background iframe:
