Neural Network — Signals Through Neuron Layers

Signals through neuron layers, in one HTML file. Hover trace, click inference.

Signals through neuron layers, built entirely in code: one self-contained HTML file with no images, no 3D models and no build step. Under the hood: Three.js, instanced neurons with activation attribute, 400+ synapse lines, travelling signal pulses, UnrealBloom. What a visitor can do: hover a neuron to trace its connections, click to fire an inference (or a single neuron), 4 presets (Cyan, Magenta, Matrix, Paper). Best for: AI, machine learning, data, deep-tech brands. 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.
