things to stare at instead of working

Six self-hosted toys — cellular automata, flocking, gravity, fractals, particle life, fluid dynamics. Nothing to install, nothing saved, just click and mess around.

Game of Life

🟩

Conway's cellular automaton. Draw a pattern, hit play, watch it live or die.

Boids

🐦

Flocking simulation — hundreds of agents following three simple rules, moving like a flock of birds.

move mouseopen

Gravity

🪐

N-body gravity sandbox. Drag to launch a mass with a real inverse-square pull on everything else.

click + dragopen

Fractal

🌀

Mandelbrot & Julia set explorer. Scroll to zoom, drag to pan, infinite detail the whole way down.

scroll + dragopen

Particle Life

🦠

Colored particles pull and push each other by type — random rules, cell-like emergent life every time.

randomizeopen

Fluid

💧

Real-time WebGL fluid dynamics. Drag across the canvas to stir up smoke-like color.
