From the README

An interactive flocking simulation in the browser, built with plain HTML and vanilla JavaScript — no build step, no dependencies.

Hundreds of boids follow three local rules — keep apart, line up, stay together — and a flock emerges. Tune the rules live and watch it tighten into a school, scatter into a swarm, or ripple away from your cursor.

Then open the printed URL in a browser.

Murmuration (balanced), Fish school (strong alignment, one turning body), Swarm (cohesion without alignment, a buzzing cloud), Scatter (separation only) and Lanes (alignment only, parallel traffic streams).
