2D rigid-body physics engine with collision, constraints and composites, frequently repurposed to make UI elements tumble and stack.

Cross-platform 3D rigid body physics engine written in Haxe with a JavaScript build, joints and broadphase options.

Tool and library for generating CSS keyframe animations from physics presets like bounce, hardbounce, sway and wobble.

Game engine layering sprites, animation, groups and Box2D physics on top of p5.js/q5.js for creative coders.

TypeScript rewrite of Box2D with an idiomatic JS API, joints, sensors and continuous collision for web and mobile.

Physics-based smooth cursor component for React with spring stiffness, damping and rotation-on-velocity options.

Claude Code skill that turns a one-line machine description into a photoreal three.js simulation in one HTML file, driven by a small real physics solver.

Cartoon ragdoll sandbox in the browser with 25 ways to ruin Wumpus's day, built on Three.js and Rapier physics with no build step or assets.

Browser gravity playground with deterministic time scrubbing, fully editable bodies, preset solar systems, unlockable missions and a user-submission gallery.

WebGPU solver that simulates fluid and rigid bodies as one position-based-dynamics system, with screen-space fluid surface reconstruction.

Channel teaching the mathematics programmers actually need: vectors, trigonometry, easing, physics and parametric motion.

Spring-physics animation library that interpolates any value type and runs off the React render loop for imperative performance.

Library of real-time physics simulations — pendulums, springs, collisions — with editable parameters and published equations.

Library that converts spring physics parameters into easing keyframe arrays consumable by WAAPI, GSAP, Motion or CSS.
