whatA handful of animals wander from their dens, and the ground tessellates into territories with borders that never quite stop drifting. Click an animal to remove it and its neighbours annex the ground, border by border.

whyNo fights, no fences, no map, yet territories with stable borders appear. The piece shows how ownership can be an emergent thing, a standoff between scents rather than a line anyone drew.

howEach walker leaves scent wherever it steps, and scent fades over half a minute. A walker that smells another's fresh scent ahead turns away from it. Nothing else. Each walker ends up owning the region it can keep freshly marked, roughly the cell around its den. Borders are bold where the scent on both sides is fresh and contested, thin where it is stale. Click empty ground to add a walker; the trace at top right is how much ground changed hands lately.
