Slime mold — Physarum slime mold simulation

Physarum agents sense, turn, step, deposit; the trail map diffuses and decays each frame. Cursor deposits attractors; click drops a burst.

How it works

Physarum agents — sense, turn, step, deposit. Trail map diffuses and decays each frame.

Cursor deposits trail attractors; click drops a burst. LUT maps trail intensity → magenta → orange → yellow → white.

• BoidsReynolds 1987 boids — separation, alignment, cohesion — running on a spatial hash grid. Cursor attracts the flock; click repels. Torus wraparound.
• NeuronsTwo nearby neuron fields linked by only a handful of short bridge connections. Click starts a session — nearest neuron fires, then pulses spill unpredictably between the two clusters.
• Lightning treeLightning branches downward from clouds toward the cursor in a fractal pattern. Mountains silhouette the horizon.
• Lorenz attractorFour points integrate the Lorenz system (σ=10, ρ=28, β=8/3) — the butterfly attractor. Cursor pulls the integration target; click reseeds.
