Ten fruit flies, wired from a real fly's connectome, learn to find the striped guy. Then you race one.

▶ Play it in your browser (phones too)

Each fly sees through an eye with a real fly's facet count and learns with mushroom bodies (the fly brain's learning centers) wired with that fly's real connections, taken from its complete wiring diagram. Land on the striped guy: sugar. Land on anyone else: a zap. Flies that can't learn find him about 1 time in 8. Flies that learn pass 8 in 10 within about ten rounds and settle at 9 in 10.
