what it is

A real organism, not a metaphor

Every neuron in this specimen has been traced. There are none. The nervous system was reconstructed in full in 0.4 milliseconds, verified by three independent labs, and is released under CC0 because there is nothing to license.

Zero synapses were dropped for having fewer than three connections, because zero synapses exist. The sign of each connection — excitatory or inhibitory — is not applicable. Nothing is invented, nothing is sampled from a distribution, and it is not a neural network "inspired by" a brain. It is a sponge.

how it reaches the world

It senses with its whole body and decides with none of it

A sponge does one thing: it pumps water. Inhalant pores draw it in, flagellated chambers push it through, and a single exhalant opening — the osculum — lets it out. That flow is the entire behavioural repertoire of the animal, so that is what drives the cursor.

osculum
Exhalant flow rate, sampled at 10 Hz by a thermistor anemometer positioned 2 mm above the opening. Above the 30-minute baseline drives BUY, below drives SELL.
→ cursor y · decision
ΔT L/R
Water temperature on the left versus right side of the tank, 0.01 °C resolution. A sponge cannot steer, so the water steers for it.
→ cursor x
sneeze
Sponges periodically contract their whole body to flush sediment. This is real, documented, and takes between 20 minutes and several hours. Here it is the click.
→ click · execute
eye
892 retinotopic columns were allocated. None are connected to anything. A screenshot of the live page is sampled into them at 30 × 30 and discarded, for consistency with prior work.
→ nothing
live run

Watch it fill the form

Every run the sponge is put in front of the launchpad with a real cursor. Its oscular flow drives y, thermal asymmetry drives x, and a sneeze is the click. Whatever it misses, a script completes — and the log labels which was which. Nothing on this page can launch anything. The button says so.

the plan

Released. It did not notice.

Not a roadmap of promises — a sequence. Everything above the amber line is done and checkable. There is nothing below the amber line.

Closed the reward loop

Profit and loss are both piped into the tank as food. It cannot tell the difference.

Gave it a nose

It is, in the strict sense, entirely nose.

Release

A budget, an open browser, no schedule and no instructions. It has been sitting in the same spot for 11 months.

$NOBRAIN

Launched by the sponge, from the sponge's own wallet. Read the receipt yourself rather than taking this page's word for it. This page has no brain either.
