Four pictures

  1. A fruit fly in close-up: big red eyes, two wings, six legs

    This is a fruit fly.

  2. A render of the real fly brain from the connectome, with its two mushroom bodies glowing orange

    Its brain, mapped neuron by neuron.

  3. A render of one mushroom body split into its sixteen compartments, good ones orange, bad ones blue, each labelled

    Deep inside is the mushroom body: 16 rooms, each saying good or bad.

  4. A bar chart with one row per compartment: bars to the right for good, dithered bars to the left for bad

    vaxenfly pushes your agent's state through those rooms and reads 16 good/bad numbers.

No dependencies. About 0.65 ms per read.
