Ornate fractal lace scrollwork growing from corners with dark metallic rendering.
What is Gothic Filigree?
Gothic Filigree is a free WebGL web effect in the TappyPrism library. Ornate fractal lace scrollwork growing from corners with dark metallic rendering. 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 (gothic-filigree.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Growth Speed, Curl Tightness — adjustable in the browser or at runtime.
Parameters
| Parameter | Key | Range | Default |
|---|---|---|---|
| Growth Speed | GROWTH_SPEED | 0.3 – 3 | 1 |
| Curl Tightness | CURL_TIGHTNESS | 0.3 – 1 | 0.7 |
