N-BODY

N-body gravity simulation. Particles attract each other and trace orbits.

MOBIUS FLOW

Particles flowing on a Möbius strip. Luminous trails drift slowly across a twisted surface.

L-SYSTEM GARDEN

L-system branches grow slowly into a luminous garden and sway with wind.

CYCLIC CA

Cyclic cellular automaton. States chase each other to form luminous spirals and wavefronts.

LEVY DRIFT

Lévy flight. Luminous trails shaped by short wanderings and sudden long leaps.

BÉZIER

Bézier curves. Interpolation of interpolations — visualizing the de Casteljau algorithm.

ISING

Ising model. Spins on a lattice flip via Metropolis algorithm, forming beautiful domain structures near the critical temperature.

EPIDEMIC

SIR epidemic model. Waves of infection sweep across a grid. β controls spread speed, recovery shapes the wave.

NEWTON

Newton fractal. Visualizing Newton-Raphson convergence to roots of z^n−1=0 in the complex plane. The basin boundaries are fractal.

CLIFFORD

Clifford strange attractor. Two simple equations, four parameters, infinite patterns emerge as millions of points accumulate.
