Aurora Veil
Northern lights ribbons flowing above hexagonal ice crystal formations.
What is Aurora Veil?
Aurora Veil is a free WebGL web effect in the TappyPrism library. Northern lights ribbons flowing above hexagonal ice crystal formations. 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 (aurora-veil.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Aurora Speed, Intensity — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Aurora Speed | AURORA_SPEED | 0.1 – 1.5 | 0.5 |
| Intensity | AURORA_INTENSITY | 0.3 – 2 | 1 |
