Particle demos you can play right now

Over a hundred particle demos, each running live on its creator's own site: some of them vibe-coded with AI, all of them playable in your browser with nothing to install. Press a card to play one on its own page, or start the cruise to ride through them one after another.

Thousands of tiny points with simple rules, moving together until they look like smoke, fire, galaxies or a flock of birds. Particle systems are the classic eye candy of creative coding, and most of these react when you move the mouse through them. Most have a slider or two to play with, and none of them can be won. If these are your thing, the fluid demos push the same idea toward water and smoke, and the fractals and the Game of Life are other simple rules that unfold on their own.

Controls are usually the mouse: move to stir them, click to burst or attract.

Questions about particles

What is a particle system?

A technique where many small elements each follow simple rules for position, velocity and lifetime. Together they model things with no fixed shape, like smoke, sparks, water or swarms.

How can a browser move so many particles?

Small counts run fine on a 2D canvas. For tens of thousands or millions, projects hand the work to the graphics card with WebGL or WebGPU shaders.

How do I interact with them?

Move, click or drag the mouse through the field; many attract or scatter the particles around the pointer. Some use the webcam or microphone instead and will ask first.
