A Gray-Scott reaction-diffusion field whose feed and kill rates vary by location across the plate, so different regions grow different Turing patterns — spots, worms, coral, maze — that meet and interfere along their boundaries. A warm garden palette tints each zone by its local parameter. It seeds and evolves on its own; drag injects chemical, scroll drifts the parameter map so the zones migrate, and a press reseeds a fresh growing region under the pointer.
