Particle Life
Artificial life simulation where simple attraction and repulsion rules between particles produce complex emergent behavior.
About Particle Life
Hundreds of colored particles fill the screen, each type pulling toward some neighbors and pushing away from others. You tweak a single attraction value and watch what was a chaotic cloud slowly coil into rotating clusters, living threads, or colony-like blobs that hunt and scatter. No two rule sets produce the same result, and small adjustments cascade into behavior that genuinely looks alive.
It belongs squarely in the interactive simulation space, alongside tools built around emergence and self-organization. If you enjoy this kind of bottom-up complexity, Ant Colony offers a similar thrill through AI ants building pheromone trails from equally simple rules.
Mouse or touch controls let you drag particles and nudge the simulation while it runs. It works best on a desktop where you can keep the parameter sliders open on one side and the canvas on the other — watching a rule change ripple through the whole system in real time is where it clicks.

How to use
Watch colorful particles interact and form complex patterns through attraction and repulsion forces. • Click on screen to create attraction pulse (Shift+click for repulsion pulse) • Press R to generate random interaction rules between particle colors • Press S to make rules symmetric (particles affect each other equally) • Press O to reset particle positions • Press T to toggle cluster tracking The simulation shows particles of different colors following programmed rules - some colors attract, others repel. Each color has customizable interaction strengths with every other color. Use the control panel to: • Adjust number of colors and particles per color • Modify time scale, viscosity, and gravity • Change visual settings like particle size and background • Export images or videos of interesting patterns • Set custom interaction rules between colors Goal: Experiment with different rule combinations to create emergent behaviors like clustering, oscillations, or chaotic movement. Try symmetric rules for stable systems or random rules for unpredictable dynamics.
