Physarum - Slime Mold

Physarum is a visually rich simulation inspired by the behavior of Physarum polycephalum, a real-life slime mold known for its ability to form networks, solve mazes, and demonstrate decentralized intelligence — all without a brain. Using thousands of autonomous agents, the app models how simple behaviors like sensing, turning, and trail-following can lead to mesmerizing, complex patterns. Agents detect pheromone trails in their environment, steer toward stronger signals, move forward, and leave trails of their own — creating a continuously evolving system. With an intuitive UI, you can: - Adjust agent parameters: sensor range, angles, movement, and trail strength - Explore chaotic, branching, or self-organizing behaviors - Save and restore interesting formations - Visualize trails using vibrant color modes - Tap, paint, and nudge the system to influence its growth Whether you’re curious about artificial life, fascinated by emergent systems, or just enjoy watching hypnotic patterns, Physarum offers a meditative and educational experience like no other.
