Lightning tree — branching lightning simulation

Lightning branches downward from clouds toward the cursor in a fractal pattern. Mountains silhouette the horizon.

How it works

Branching lightning grows downward from clouds toward the cursor (or strikes randomly). Mountains silhouette the horizon.

• Slime moldPhysarum agents sense, turn, step, deposit; the trail map diffuses and decays each frame. Cursor deposits attractors; click drops a burst.
• 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.
• Lorenz attractorFour points integrate the Lorenz system (σ=10, ρ=28, β=8/3) — the butterfly attractor. Cursor pulls the integration target; click reseeds.
• FireworksRockets launch from a skyline silhouette and burst into chrysanthemum, willow, ring, or crossette patterns. Click for a burst.
