Where the fly is right now

A page goes in through 892 hex columns, 165,122 neurons integrate, and a cursor comes out. Every number below is read out of the running simulation.

where it has been

No wallet, no keyboard, no downloads. Every click is checked before it lands and vetoed if it looks like it commits something — a submit, a sign-in, a purchase.

what it is

A real nervous system, not a metaphor

Every connection in this thing was traced from electron microscope images of an actual male fruit fly. Nothing is invented, nothing is sampled from a distribution, and it is not a neural network "inspired by" a brain.

The male Drosophila CNS connectome was released in September 2026 by HHMI Janelia FlyEM, the Cambridge Connectomics Group and Google Research, under CC-BY. We keep the 165,122 neurons marked traced, drop pairs with fewer than three synapses, and take each connection's sign from its predicted neurotransmitter — acetylcholine excites, GABA and glutamate inhibit. The neurons run as leaky integrate-and-fire units: rest −52 mV, threshold −45 mV, 20 ms tau.

how it reaches the world

It sees with a fly's eye and moves with a fly's legs

A screenshot of a live web page is sampled through 892 retinotopic hex columns into L1 and L2 — the lamina monopolar cells sitting directly behind photoreceptors R1–R6. All 165,122 neurons integrate. The cursor comes back out of the descending neurons a fly actually walks with.

DNa02

Left versus right. A fly steers by asymmetry between the pair, so the difference drives the cursor's x.

DNa01

Forward walking. Drives the cursor's y.

MDN

The Moonwalker neuron. Makes a fly walk backwards; here it reverses.

DNp09

Stopping. A fly freezes when it fires, so it became the click.

the plan

Being trained to be free

Not a roadmap of promises — a sequence, with everything before the amber line already done and checkable in the repo.

what is not real, stated plainly

The parts that aren't the fly

The fly does not fill the whole form. It reliably gets the description, often the ticker, rarely the name. A script completes what it misses, picks the paired asset and sets the creator tax — and the live log labels which was which.
It cannot read. 892 columns is roughly a 30×30 pixel view. Text is texture to it, so it targets any unfilled box rather than the right one.
Light mode blinds it. Its retina is a luminance map and all of its tuning was done against dark interfaces. On a light page it filled 0 of 3 fields; on a dark one, 2 of 3. That gap is the clearest evidence the eye is doing real work.
It has no goals. A fly brain has no language and no plan. Releasing it means nobody is steering, not that it decided anything.
It is not released yet. Step 08 is locked. Today a script still starts each run.
