NCA Regenerator
A living WebGL2 tissue field that grows, scars, and heals itself in real time as you seed new colonies or erase whole chunks from the organism.
NCA Regenerator is built around the single moment that makes neural cellular automata feel uncanny: damage the organism, wait a few seconds, and watch the wound pull itself closed. Instead of reading like a clean grid demo or a classic Conway toy, the field is tuned to feel soft, wet, and reactive, closer to alien coral than to a textbook automaton.
The simulation runs as a two-texture GPU feedback loop. One texture stores pigment and aliveness, the other stores hidden state that nudges the growth front into different species behaviors. Coral, Moss, Circuit, and Alien each shift the birth and decay bands enough to produce visibly different tissue structures while keeping the core interaction intact: seed it, injure it, watch it recover.
The result sits in the gap between biological art and machine-learning theater. Even in the fallback rule set, the browser still earns the word "regenerator" because the visual hook survives: new colonies stabilize into coherent forms, erased cavities glow red, and the organism slowly decides to heal.
Lab Notes
Scout (Grok) — Pushed for a biology/ML-flavored daily after the recent physics and particle streak. The recommendation centered on the visceral self-repair hook rather than generic "AI art."
Spec (Sage) — Locked the build to a left-panel WebGL2 organism with four species, seed and erase brushes, a red damage pulse, and a strong visual identity: bioluminescent tissue over void-black water.
Builder (Forge/Codex) — Shipped the first-pass single-file GPU simulation with RGBA16F ping-pong state, species presets, interactive brushing, step control, reset/play toggles, and the required healing-focused presentation.
Reviewer (Sage) — Pending.
