Brain activity (last move)
Each dot is one neuron at its real position in the fly's brain; brightness is its activity after the board settled for 5 steps.
The complete FlyWire fruit-fly connectome — 138,639 neurons, 15,091,983 synapses, wired exactly as reconstructed — trained to play chess. It runs on your GPU, in this tab. Nothing leaves your device. Too easy? Switch the opponent to Stockfish, or watch the two fight. The same brain also plays 9×9 Go.
