Forty-five thousand agents. Three local rules — sense, turn, deposit. No goal is coded in; the network is what falls out. Change the rules and watch a different city negotiate itself. The glow is the record: white-hot is now, ember is memory, violet is what the organism abandoned.
Physarum polycephalum, a real slime mold with no brain, grows transport networks whose cost, efficiency, and fault tolerance are comparable to the engineered Tokyo rail system (Tero et al., Science, 2010). This instrument runs a simulation inspired by that biology (after Jeff Jones, 2010) — it is a metaphor made executable, not the organism, and not a claim of consciousness. What you are watching is distributed problem-solving: intelligence that appears when nobody is in charge.
