Physarum · agent transport network

Physarum Reef

A colony of ~18,000 blind agents lays down a chemical trail, follows it, and — through nothing but deposit, diffuse and decay — condenses itself into a breathing vein network. Feed it real music and the organism grows differently: loudness quickens growth, brightness widens its branching, bass thickens the veins, and every onset injects a burst of fresh growth.
