Physarum - Slime Mold

Watch emergent life unfold. Physarum is a captivating, agent-based simulation of slime mold behavior, powered by simple rules and stunning visuals.

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.
