Clay Blob — Velvety Morphing Gradient Blob

Velvety morphing gradient blob, in one HTML file. Blob leans to cursor, click wobble.

Velvety morphing gradient blob, built entirely in code: one self-contained HTML file with no images, no 3D models and no build step. Under the hood: Three.js, MeshPhysicalMaterial patched with onBeforeCompile, simplex-noise displacement with recomputed normals, sheen. What a visitor can do: the blob stretches toward your cursor, click to make it wobble, 4 presets (Peach, Lilac, Mint, Midnight). Best for: Calm premium hero, wellness, beauty, fintech, AI assistants. Three.js loads from a CDN through an import map, so there is still nothing to install. Every colour, count and speed sits in one CONFIG block, presets switch live from a glass dock, and ?embed strips the interface for a clean iframe or hero background.

How to run this

Nothing to install and nothing to configure. Works in any modern browser on Windows, macOS and Linux.

Built with
Single HTML file
Requires
A modern browser
  1. 1. Unzip the download.
  2. 2. Double-click index.html. It opens in your browser and runs. To serve it instead (the microphone and some browsers want a server), run npx serve . in the folder and open http://localhost:3000.

Note — Three.js loads from the jsDelivr CDN through an import map, so the first load needs an internet connection. Add ?embed to hide the interface for an iframe or hero background, and ?preset=N to start on a colour preset.
