Field notes
The page describes a steering loop that runs every 10 milliseconds: target direction drives activity through mapped neural connections, turn-command neurons set the direction, and the fly’s simulated feet leave paint on the canvas. Its brain model is described as 138,639 neurons and about 15 million connections. The featured Mona Lisa and Starry Night paintings are playback runs; the page separately presents a live visual-system mode.
