A field of ideas,
alive under your pointer.

Across the canvas, a seeded population leaves one short segment per frame. Moving through open space redirects nearby points inside a 210px field; pressing raises the input gain. The line you perceive is accumulated light, not recorded geometry.

Two losses shape the result. Velocity damping removes kinetic memory; a time-corrected dark wash erases optical memory faster. Their difference keeps a response legible without allowing old frames to pile up indefinitely.

Every point keeps two accounts: its displacement from home and its disagreement with up to four orthogonal neighbors. Pressing the open field pulls a 220px patch. After release, neighbor coupling redistributes that error while damping removes it.

This is a coupled spring lattice, not a cloth solver. There are no hard length constraints, diagonal fibers, pinned edges, collisions, or explicit mass. Its product value is narrower: adjacent elements can acknowledge one change, then settle.

Two concentration fields begin from nine authored patches. Seed zero keeps their exact positions; a new seed makes one bounded, deterministic variation before the solver starts. Each update then diffuses A and B through a nine-point stencil, converts A into B, replenishes A at 0.055, and removes B with a 0.062 kill rate. No randomness enters the update itself.

The field is allocated only when this chapter is entered. Its 300 setup iterations are spread across roughly half a second. At the authored control value, live evolution advances at 180 iterations per second and pointer patches span 3.5 cells; Growth rate exposes the bounded 90–270 and 2.5–4.5 ranges. The grid stops at 32,768 cells. The bright copper band near 0.48 is an authored color transfer—not biology or measured data.
