Watch a slime mold agent simulation grow branching, organic networks live in your browser, free and with no install. Thousands of simple agents sense a shared pheromone trail with three sensors and steer toward the strongest signal, the same simple local rule real Physarum slime mold uses to solve mazes and connect food sources. Pick a colony personality (tight Veins, branching Web, space-filling Blob, or wandering Coral), choose a bioluminescent color palette, and tune population, speed, sensor angle, turning, and trail fade to reshape how the colony grows. Tap or drag on the canvas to drop food and watch the colony reach for it. Nothing uploads anywhere — the whole simulation runs locally. Save any moment as an image or copy it to the clipboard to share.
