Eight interactive SDF scenes rendered per-pixel via sphere tracing. Navigate mathematically-defined 3D worlds — infinite detail, zero polygons.

IFS fractal flame generator with 21 variation functions. Log-density rendering, 7 presets, 5 palettes.

Interactive Navier-Stokes fluid simulation. Click and drag to inject dye and velocity into a real-time pressure solver.

Real-time fluid surface simulation with autopilot mode and wallpaper recording. Touch the water and watch interference patterns propagate.

Terrain sandbox with tectonics, hydraulic erosion, and meandering river channels. Sculpt landscapes and watch water carve them over geological time.

Diffusion-limited aggregation — random-walking particles build coral, lightning, and frost structures. Real-world presets with tunable stickiness.

Fractal basin explorer. Drop a pendulum over magnets and map which one captures it — the boundaries between basins form infinitely complex fractals.

Lattice Boltzmann fluid simulation. Place obstacles and watch vortex streets form in real time. Adjustable Reynolds number with context-aware education panel.
