Mathematics & Fractals

794 demos · 25 galleries

The visual heart of CCAB. Mandelbrot and Julia sets, Lorenz and chaos attractors, Penrose tilings, fractal flames, L-systems, space-filling curves, and cellular automata push pixels into territories where algebra becomes art. Includes interactive explorations of knot theory, non-Euclidean geometry, probability paradoxes, and 514 surprising mathematical paradoxes that challenge intuition.

Art, Animation & Creative

807 demos · 48 galleries

Where code becomes canvas. Generative art, GPU shaders, WebGL and WebGPU graphics, Three.js 3D scenes, music sequencers, satisfying loops, screensaver patterns, and creative coding with p5.js and D3.js. Also home to poetry, storytelling, visual essays, optical perception experiments, sound art, and cultural explorations -- proof that algorithms have an aesthetic life of their own.

Physics & Mechanics

222 demos · 18 galleries

Classical mechanics to fluid dynamics in interactive form. Pendulums swing into chaos, Navier-Stokes streamlines flow past obstacles, cymatics patterns emerge from vibrating surfaces, and thermal diffusion spreads through grids. Collection galleries consolidate the best of fluids, collisions, pendulums, heat transfer, tidal mechanics, and optics into rich explorable sets.

Biology & Ecology

308 demos · 25 galleries

Life simulated at every scale. Flocking boids swarm, epidemics spread through contact networks, predator-prey cycles oscillate, and altruism evolves through iterated games. From morphogenesis patterns to bioluminescent deep-sea creatures, coral reef ecosystems to mycelium networks -- these demos model the algorithms life runs on.

Computer Science & Algorithms

247 demos · 23 galleries

Algorithms made visible. Watch sorting algorithms race, pathfinding agents navigate mazes, neural networks learn in real time, and cellular automata compute with simple rules. Data structures from binary trees to graphs, cryptographic primitives, machine learning playgrounds, game AI strategies, and Wolfram's elementary automata -- the theory of computation rendered as interactive experience.

Engineering & Technology

301 demos · 36 galleries

Applied science in action. PID controllers tune themselves, robot arms solve inverse kinematics, Kalman filters track noisy signals, and Jansen linkage mechanisms walk across the screen. Also features a deep History of Computing collection spanning ancient calculators, Renaissance instruments, cipher machines, and the dawn of electronic computing.

Earth & Space Science

174 demos · 13 galleries

From solar flares to ice sheets. Galaxy collisions unfold over millions of years, orbital flythroughs recreate historic spacecraft missions, and stellar evolution traces a star's lifecycle. Explore volcanic eruptions, glacier dynamics, ancient celestial navigation, and constellation myths alongside the Climate & Weather collection.

Economics & Social Science

158 demos · 16 galleries

Markets, societies, and strategic minds. Game theory payoff matrices, Schelling segregation models, wealth distribution dynamics, voting theory paradoxes, and electoral system comparisons. The Financial Models collection consolidates stock walks, Monte Carlo options, bank run cascades, and market dynamics into one explorable gallery -- the invisible hand, made visible.

Simulation Platforms & Collections

801 demos · 18 galleries

The mega-collections. Three NetLogo simulation suites alone contain 598 agent-based models spanning ecology, economics, physics, and social science. Emergent behaviors, scientific visualizations, quantum mechanics, chess variants, and curated educational galleries round out the largest demo count in any category. These are the treasure troves for deep exploration.

Chemistry & Materials Science

32 demos · 14 galleries

Atoms, bonds, and crystal lattices. The Belousov-Zhabotinsky reaction oscillates in mesmerizing spirals, alloy phase maps reveal metallurgical boundaries, and molecular orbitals glow in 3D. From Le Chatelier equilibrium shifts to polymer chain dynamics, galvanic cells to forensic analysis -- the molecular world in miniature, one reaction at a time.
