Neon Drip

Metaball blobs dripping upward with surface tension physics and trailing tendrils.

What is Neon Drip?

Neon Drip is a free WebGL web effect in the TappyPrism library. Metaball blobs dripping upward with surface tension physics and trailing tendrils. 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 (neon-drip.html) with zero dependencies — no npm package, no framework, no build step. It exposes 2 live parameters — Drip Speed, Blob Count — adjustable in the browser or at runtime.
