Matrix Effect
Runic characters fall in columns, each leaving a fading trail behind it. Inspired by the digital rain from The Matrix.
Conway's Game of Life
A zero-player cellular automaton. Each generation, cells live or die based on their live neighbor count — fewer than 2 or more than 3 kills a cell; exactly 3 births a new one.
Spring Trail
A chain of dots following the cursor with spring physics. Each dot springs toward the one ahead of it, creating an elastic bouncing trail.
Perlin Flow Field
Thousands of particles drift along an invisible vector field driven by smooth noise. Trails fade slowly, leaving flowing, smoke-like streams that shift over time.
Fourier Epicycles
Any closed curve can be approximated by a sum of rotating circles. A Discrete Fourier Transform decomposes a heart shape into frequency components, then animates the epicycle chain drawing it back.
Boids
Emergent flocking behaviour from three simple rules: avoid crowding neighbors (separation), steer toward average heading (alignment), and move toward the center of the flock (cohesion).
Fractal Tree
A recursively branching tree where each branch splits into two at a configurable angle. Outer branches sway gently with wind. Adjust depth and angle with the sliders.
Double Pendulum
A pendulum hanging from another pendulum. Deterministic physics — yet the motion is chaotic and never repeats. Enable "chaos" to show a second pendulum offset by 0.001 rad: they diverge rapidly.
Sand Simulation
A falling-sand cellular automaton. Each material follows simple physics rules — sand piles up and slides, water flows sideways, fire rises and ignites sand.
