We turned a fly's brain into the world's smallest billboard. Type your brand or drop in your logo, it lights up the neurons inside a real simulation of the fly's brain, and the fly tells you what it thinks: it gets curious, it reaches for food, it turns away, or it panics. You get an 11-second clip of it.

Type your brand or drop in your logo. Every lit point is a real neuron, at its real position in the brain.
Save the clip, then attach it to your post.
“Make my clip” runs all 138,639 neurons right in your browser, then records an 11-second video. Keep this tab open while it records. Your logo never leaves your device. On phones it can take a minute or two.
Every brand gets the same brain, so nobody gets a better mood by asking nicely. Fun labels, real neurons: hungry is its tongue neuron compared with a real sugar taste, curious is its antenna neurons, and brain cells lit up is how much of its brain fired.
The idea: one fly, 1,440 minutes a day, and brands take turns living rent-free in its brain. Nothing is for sale. If you'd want your brand in there, tell me. Enough yeses and I'll build it.
Real: the brain wiring (the FlyWire connectome, all 138,639 neurons), the neuron model from Shiu et al. 2024, and every neuron's position. Which neurons join in and what the brain tells the body comes from the wiring, not a script. Your logo never drives the fly's output neurons directly (its descending and motor neurons are skipped), so what the fly does has to come through the wiring.
Not real: no animal sees your logo; it's a computer simulation. The fly's body is animated from its output neurons, and the mood labels are playful names for real neuron activity.
No, and that's the fun part. Your logo lights up a different set of neurons than anyone else's, so the wiring gives every brand its own reaction. Some flies turn, some reach for food, some try to escape.
A square clip of your logo firing through the brain with the fly reacting next to it, plus its dopamine verdict. Post it wherever you like.
Maybe. Appetite measures the fly's proboscis motor neuron (MN9, the one that sticks its tongue out) against a real sugar taste in the same model. Results differ by brand and a little from run to run. Its dopamine reward neurons are a tougher crowd: they have stayed quiet for every brand so far.
Your own brand or product. No hate, adult content, scams, or logos you don't have the right to use.
Not yet. This is an experiment. If you'd want your brand in there, DM @fulutmd and say so.
