Guide organic networks, paint trails, and watch artificial life grow in a real-time Physarum simulation. Explore artificial life through a living, flowing simulation inspired by Physarum polycephalum, the slime mold famous for forming networks, solving paths, and showing intelligence without a brain. Physarum turns simple local rules into complex motion. Thousands of agents sense trails, turn, move, and deposit new traces. As the field evolves, branching networks, waves, and organic textures emerge in real time. Use Physarum to: - Tune sensor distance, turn angle, movement, and trail strength - Paint into the field and guide the simulation by touch - Explore chaotic, branching, and self-organizing patterns - Save and restore interesting agents, fields, and rules - Create vivid generative visuals with color controls It is part science toy, part generative art studio, and part meditative visual instrument. Whether you study emergent systems, teach artificial life, or simply enjoy hypnotic motion, Physarum gives you a hands-on way to watch complexity grow from simple behavior.

Tesselations screen grab?
Apr 7

I get the impression the whole image area tiles the plane if I’m correct I don’t see an easy way to get a screen grab without all the little icons??? that would be a great new feature? unless it’s a quadruple tap or something.

Hi! Thank you for your request. Now you can only minimize these menus, but you’ll still have bottom icons. I’ll put the feature to my priority list
