morph runs the Gray-Scott reaction-diffusion model: two virtual chemicals, U and V, spread across a grid and react with each other. V consumes U to make more of itself, while a steady feed tops up U and a kill term removes V. From this single rule, run at different feed and kill rates, wildly different structures grow.
In 1952 Alan Turing proposed that the interplay of a fast-spreading inhibitor and a slow-spreading activator could break a uniform field into patterns. The same machinery is thought to shape animal coats, shell markings, and tissue structure. Tiny shifts in the parameters flip the system between self-replicating spots, branching coral, labyrinthine mazes, and crawling worms.
Describe a hypothesis in plain language and the lab designs an experiment, runs control and treatment groups, and reports the outcome with proper statistical tests and effect sizes.
morph is one of several interactive simulation playgrounds in the petri-labs collection.
