As each swings and slowly decays, their combined motion traces a curve...→Chladni FiguresSand on a vibrating plate migrates to the nodal lines — places where the plate doesnt move. The...→Penrose TilingA tiling that never repeats but is never random. Roger Penrose discovered in 1974 that two shapes —...→Brownian MotionA particle jostled by invisible collisions traces a path that looks random but obeys deep laws....→SIR EpidemicThree states, one equation. Susceptible individuals become Infected, then Recovered and immune. The...→Kuramoto ModelSynchronization from chaos. Each oscillator has its own natural frequency, yet above a critical...→Collatz ConjectureTake any positive integer. If even, halve it. If odd, multiply by 3 and add 1. Repeat. Does it...→Particle LifeParticles of different species attract and repel each other according to a matrix of interaction...→Cloth SimulationThousands of points connected by springs, each pulling its neighbors back toward equilibrium....→Gravitational LensingMass bends spacetime, and spacetime bends light. Behind a massive lens, stars stretch into arcs,...→SpirographWheels within wheels. A small circle rolls inside a large one, tracing curves of startling...→Chaos GameFractals from dice rolls.

Pendulums of carefully tuned lengths start together, drift apart into...→Wave Function CollapseStructure from constraint. Each cell begins in superposition — all tiles possible — then collapses...→SortingOrder from comparison. Every sorting algorithm answers the same question — put these elements in...→MazeStructure from constraint. Each algorithm carves passages by removing walls, but different rules...→Elementary CA256 possible rules, one dimension, infinite variety. Each cell looks at itself and its two...→VoronoiGiven a set of points, divide the plane so every location belongs to its nearest point. The result...→Wave EquationA membrane vibrating in two dimensions. Click to strike it, drag to draw walls. Waves reflect,...→Game of LifeFour rules, two states, infinite complexity. A cell is born if it has exactly three neighbors. It...→Ising ModelA grid of tiny magnets, each pointing up or down. Below a critical temperature they spontaneously...→PercolationEach cell is independently alive with probability p. Below a critical threshold, all clusters are...→Diffusion-Limited AggregationStructure from noise. Random walkers drift aimlessly until they touch something solid and freeze in...→BoidsNo leader. No choreography. Each agent sees only its neighbors and follows three rules — stay...→Magnetic PendulumPredictability has a fractal boundary. A pendulum swinging over three magnets always settles on one...→Light DispersionWhite light is a chord — a prism reveals the individual notes. Each wavelength bends by a different...→L-SystemsA formal grammar that generates fractal geometry. An axiom, a handful of rewrite rules, and a...→GravityNewtonian gravity between point masses. Place bodies by clicking the canvas, or load a preset to...→LeniaContinuous cellular automata.

For ten...→SandpileDrop sand one grain at a time. When a cell reaches four, it topples — sending one grain to each...→Reaction DiffusionTwo chemicals. One activates, one inhibits. Turing proposed this in 1952 as the mechanism behind...→Double PendulumThe simplest mechanical system that produces chaos. Two rigid arms connected by frictionless joints...→Op ArtGeometry as perceptual illusion. Pure line and repetition — no colour, no shading — yet the eye...→Mandelbrot ExplorerThe boundary between bounded and unbounded — rendered.
