Jellyfish Drift — Bioluminescent Jellyfish
Bioluminescent jellyfish, in one HTML file. Jellies follow cursor, startle.
Bioluminescent jellyfish, built entirely in code: one self-contained HTML file with no images, no 3D models and no build step. Under the hood: Three.js, pulsing fresnel bell shader, follow-the-leader tentacle chains, UnrealBloom. What a visitor can do: jellies drift toward the cursor, click startles nearby jellies (they dart away and flash), 4 presets (Biolume, Coral, Toxic, Abyss). Best for: Ocean, wellness, science, ambient backgrounds. 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. Unzip the download.
- 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 openhttp://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.
