Liquid Gold
Molten metal flow with surface tension, metallic PBR shading, and golden reflections.
What is Liquid Gold?
Liquid Gold is a free WebGL web effect in the TappyPrism library. Molten metal flow with surface tension, metallic PBR shading, and golden reflections. 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 (liquid-gold.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Flow Speed, Viscosity — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Flow Speed | FLOW_SPEED | 0.1 – 1.5 | 0.4 |
| Viscosity | VISCOSITY | 0.2 – 1 | 0.6 |
