Watch order spread, settle, and find its path.

Click anywhere to drop a source of order, and watch it spread and settle across the grid in real time, following a simple physics rule (diffusion with decay). The pale line is the cheapest route through the field, bending toward the bright corridors as they form. Every cell is computed live by Coherence Language compiled to run in your browser, with no chart library and no physics faked in JavaScript. It is a small working model of how heat, influence, or information spreads and finds the path of least resistance.

Click the field to place a source · drag a source to move it · right-click a source to remove it.

The coherence length is the whole story. Raising D lets coherence diffuse farther before it decays; raising Γ makes it die faster. Their ratio sets ℓ = √(D/Γ), the distance a source's coherence reaches. Where two sources sit closer than ℓ, their fields merge into a bright bridge, a corridor, and the least-cost route dives through it, because a step into a high-τ cell is cheap (cost = β/τ). That is exactly how the lab's coherence router moves data along living corridors in a mesh instead of fighting through dead space. Drag the decay up and watch the corridor close.
