Each fly steers to the knife using learned forces and rotation, then the crew banks and steadies it for a chop. Try a gust of wind to watch them recover. Fruit smell preferences are learned separately. How it works ↗
A LITTLE PRACTICE, A DIFFERENT SWARM
Smell school
Choose chefs. Pair a fruit smell with a snack. Watch their smell preferences change.
Pip + Miso are selected. Give kiwi a chance!
Peek inside a tiny brain Real circuit · simulated learning ↗
Fruit smells are synthetic inputs to a real, extracted fly circuit. Snack pairing strengthens active KC → MBON connections using an engineered game rule; the original PPL1 circuit is aversive. Preference recruits the crew. The selected flight controller supplies navigation and knife forces and rotation; flight-readout training leaves smell learning unchanged.
Tiny flies. Big slices.
Fruit Fly Fruit Ninja is a free 3D fruit-slicing game in your browser. Run a tiny salad bar, teach eight fly chefs new fruit preferences, and time each chop to fill your orders. Watch their simulated learning in the live Brain panel, then put your crew to the test in a 90-second rush.
