Robot Path Planner
Give a robot a real body and watch six search algorithms find their way through the configuration space.
The Lab Idiot
Weird projects.
See the projectsAll projects
Stats Explorer
Twenty-one real, cited datasets turn into a hands-on lab for learning statistics by doing.
Reaction-Diffusion
Two chemicals diffuse, react, and paint stripes, spots and mazes — the same math Turing used for animal patterns.
InterferQuant
An interactive double-slit experiment: watch interference build up one particle at a time.
Quantum Lab
Ten interactive quantum-mechanics experiments, built one photon at a time.
The Genetic Traveler
A genetic algorithm hunts for the shortest route through your cities.
Society Simulator
Tiny circles build a society and somehow invent inequality.
Logistic Bifurcation
Period doubling, chaos, and Feigenbaum’s universal constant.
Chaotic Billiards
Round the corners and order dies.
Strange Attractors in 3D
Deterministic equations drawing impossible geometry.
Chirikov Standard Map
Islands of order adrift in a sea of chaos.
Watts–Strogatz Small World
Rewire 1% and the world shrinks.
Bootstrap Cascades
Almost nothing ever happens. And then, everything.
Barabási–Albert vs Erdős–Rényi
Why the world has celebrities and random networks do not.
Network SIR vs Well Mixed
Same R₀, two completely different epidemics.
Herd-Immunity Threshold
The formula 1 − 1/R₀ is elegant. And incomplete.
Iterated Prisoner’s Dilemma
The tournament, evolution, and the noise that changes everything.
Spatial Prisoner’s Dilemma
Cooperation survives on geometry alone.
Hawk and Dove
Aggression has a price, and equilibrium knows it exactly.
Colour Illusions
Your eyes lie, and the eyedropper can prove it.
White, Blue and Perlin Noise
What looks random is not. And what is, does not look it.
Benford’s Law
1 leads 30% of the world’s numbers.
Lens Ray Tracer
Move the optics and discover why expensive cameras exist.
Gravitational Lensing
Mass bends space, and space bends light.
Huygens Interference
Place sources and watch wavefronts, diffraction, and interference emerge.
Entropy and Huffman
Type “aaaaaa” and watch information disappear.
The Chaos Game
Roll a die a million times and get a perfect triangle.
Boids
A flocking simulation where three local rules create coordinated motion.
Continuous Lenia
A liquid cellular automaton where continuous fields grow, travel and collapse.
Physarum
Slime-mold agents lay trails and self-organize into living-looking transport networks.
Double Pendulum Chaos
A tiny change in initial conditions becomes a completely different pendulum path.
Langton's Ant
A two-rule ant wanders randomly until a highway suddenly appears.
Schelling Segregation
Small preferences at the agent level can create large-scale segregation.
Nagel-Schreckenberg Traffic
Traffic jams appear from simple acceleration, braking and random slowdown rules.
Mandelbrot / Julia Coupler
Move through the Mandelbrot set and watch the matching Julia set update.
Diffusion-Limited Aggregation
Random walkers stick to a seed and grow branching, lightning-like clusters.
Galton Board
Falling balls build a bell curve, unless memory breaks the central limit theorem.
Lissajous Harmonograph
Coupled oscillations draw Lissajous curves and slowly decaying harmonograph patterns.
Percolation
Open enough cells and a path suddenly spans the whole system.
Kuramoto Synchronization
Many oscillators with different rhythms lock together when coupling becomes strong enough.
Pi Collisions
Count elastic collisions between blocks and a wall to reveal digits of pi.
Brachistochrone
The fastest slide between two points is not a straight line.
Wave Function Collapse
A constraint solver grows coherent tile patterns from local compatibility rules.
Pathfinding Comparator
Compare search algorithms as they explore the same maze.
Sonified Sorting
Sorting algorithms become bars, swaps and sound.
Predator Evolution Boids
Flocking agents face predators, selection pressure and evolving behavior.
