Voltage Arc
Electric plasma arcs crackling between floating conductor points with warm glow.
What is Voltage Arc?
Voltage Arc is a free WebGL web effect in the TappyPrism library. Electric plasma arcs crackling between floating conductor points with warm 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 (voltage-arc.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Arc Intensity, Crackle Speed — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Arc Intensity | ARC_INTENSITY | 0.3 – 2 | 1 |
| Crackle Speed | CRACKLE_SPEED | 0.1 – 1.5 | 0.5 |
How to add Voltage Arc to your page
- Download the standalone file voltage-arc.html and copy its source into your project.
- Or embed it as a background iframe:
<iframe src="https://prism.tappypotato.com/fx/voltage-arc.html" style="position:fixed;inset:0;width:100%;height:100%;border:0;z-index:-1" title="Voltage Arc"></iframe> - Tune it at runtime with postMessage:
iframe.contentWindow.postMessage({ type: 'param', name: 'ARC_INTENSITY', value: 1 }, '*');
