The gallery

Demos you stop scrolling for.

Each panel is a readout, not a render farm. The hex mosaic is the fly’s 892-column retina. The gauges are descending neurons a fly walks with. Lite mode is honest about the reduced mapping; full-brain mode drives the same UI from the real LIF connectome.

Motor readouts

What walks.

DNa02 L / R
Steering. A fly turns by left/right asymmetry. Cursor x.
DNa01
Forward walking. Cursor y, up the page.
MDN
Moonwalker descending neuron. Reverse.
DNp09
Stopping. The click.

Honesty

Measured, then invented.

The connectome is CC-BY — HHMI Janelia FlyEM, the Cambridge Connectomics Group, and Google Research. Simulation approach after fruitflydev/flycoinrh, Shiu et al. 2024 and Lappalainen et al. 2024. This gallery does not own that brain.

Lite mode samples the stimulus through the same 892-hex L1/L2 math as FlyEye, then uses a reduced spatial pooling onto descending neurons, decoded with FlyPilot’s equations. When graph.npz is present, those gauges come from FlyBrain.run. The mushroom-body reward signal is not real. The olfactory motor bias is demo wiring.
