An experiment in whether a market can paint a picture. 4,096 pixels, one canvas, colour from trading and nothing else. Nobody has seen the result, including me.
Your pixels
About
4,096 tokens. Each one owns a single pixel on a single 64×64 canvas. No pixel has a colour at mint. Every one starts white.
Colour comes only from what happens to a token afterward: how often it sells, how erratically, how long it rests. Nobody picks it. Nobody can see the finished image, including the person who deployed it.
| Channel | Measures | To raise it |
|---|---|---|
| Red | How many times it has sold | Trade often |
| Green | How uneven the gaps between sales are | Trade unpredictably |
| Blue | Longest unbroken hold, including the one running now | Out-hold everyone else |
| White | Never sold | Never sell |
Each channel is ranked across the whole collection and split into sixteen tones. Your pixel's colour describes where it stands against every other pixel, not an absolute number. It moves when other people trade, even if you do nothing.
That means holding is never passive. Roughly nine in ten pixels change colour over any meaningful stretch of trading, because a tone gained by one pixel is a tone lost by another.
The total climbs with every sale. At a hidden target, the sealed number, committed as a hash before launch and revealed only when the total reaches it, the canvas sets forever. The sale that reaches it is the last sale. The canvas mints as a single artwork and opens at 1 ETH with no deadline. Proceeds split equally across all 4,096 pixels, paid to whoever held each one at that block.
The winner inherits the royalties. From the moment the auction settles, the 5% royalty on every pixel sale in the collection is paid to whoever holds the canvas, not to the creator, and not to the holders. It follows the artwork: hold the canvas and you collect, sell it and the income passes to the next owner with it. That is what is actually being auctioned. Not just a picture, but every trade the collection ever makes afterward.
The sealed number may never be reached. There is no time limit and no backstop. If the total never reaches the sealed number, the painting is never finished.
No admin key, no upgrade path, no pause, no server, no indexer. The colour rules, the auction terms and the royalty destination are fixed at deploy.
Method
If you want to know why your pixel is the colour it is, this is where it is decided.
Heart
The canvas is what 4096 is. This is where it came from.
Everything on this page runs on the collection. The heart brightens when a pixel sells. It fades when nothing moves. The arteries were grown from the block 4096 was deployed in, and they reach further the longer the collection lives. None of it is a picture of the project. It is the project, read back.
The work below belongs to people who worked something out before I did. Each one built a system, then stepped out of its way. That is the idea I am working from. I am not claiming their company. I am showing you where I learned it.
The heart
The heart is craft #1154 on The Vessel. Every craft there holds exactly as many bytes as its token ID. Fifteen hundred of the ten thousand are machine crafts, which store no image at all. They hold a pointer to another contract, and when you look at one, it calls that contract and asks for bytes.
The contract on the other end is Heartbeat4096. The Vessel calls it, it reads 4096’s state, and it answers with 1,154 grayscale values. Nothing is stored anywhere along that chain. No image file, no server, no cache. The heart does not exist between the moments somebody looks at it.
Craft #1154 renders in grey, fixed when it was claimed and not something anyone can change. On this page the grid is cropped square and shaped into a heart. The Vessel’s own render is the canonical one.
Brightness
Brightness is the time since a 4096 pixel last sold, anywhere in the collection. A sale takes it to 255. From there the remaining time is raised to the power of one and a half, which is what makes the decay front-loaded. Not a straight line down, but a fast drop that flattens into a crawl.

Past seven days it is zero. One sale puts it straight back to full. There is no partial recovery and no memory of how long it was out.
The beat
Every artery cell knows its distance from the heart. The beat is that distance offset against a clock, so the crest starts at the muscle and travels out to the tips.
Rate and strength both come from the brightness. About a second per beat at full, stretching past three by day six, stopped completely at zero. A dying heart pulses faintly before it stops rather than beating hard and cutting out.
The arteries
The arteries were not drawn. A program grew them. Five trunks leave the heart, four from the top and one descending, and each walks outward one cell at a time, splitting as it goes and thinning until it runs out. Every one of those decisions comes from a single seeded random number generator.
The seed is block 25,621,173, the block 4096 and its renderer were both deployed in. That number was fixed before any of this existed, so it is not a shape I could have shopped for by growing a hundred trees and keeping a favourite. Run the same seed and you get the same tree, on any machine, forever.
How much of it you can see is the collection’s decision, not mine. The mint builds the trunks. Trading builds the fine branches at the tips. Both only ever add, so nothing that has appeared can be taken away. It is nowhere near finished.
Inspiration
In 1974 Gerhard Richter finished a painting of 4,096 coloured squares on a square canvas. It was the last work in a series he had been circling since 1966, and it ended the series so completely that he did not return to colour charts for twenty five years.
Not his painting. A 16×16 sketch of the method: 64 systematic tones, each repeated four times, placed by lottery. See the original at Sotheby's →
The original 4096 Farben sold at Sotheby's in May 2023 for $21.8 million.
Richter wanted to leave artistic feeling behind entirely, so he turned to math. He worked out exactly 1,024 unique tones by grading the primaries against greys and greens with a fixed system, made four copies of each, and then ran a random lottery to decide where all 4,096 squares would land. He painted none of the decisions himself. In the earliest colour charts he even had a friend call the colours out loud, so the selection was not his either.
What he was after, in his own words, was a diffuse, undifferentiated overall effect, a field rather than a picture. The grid, he noted, stops shapes forming, although you can find them if you insist on looking.
The part that gets us: he painted this in 1974, and it looks exactly like modern digital pixels. Decades before computers were on every desk, a math experiment on pure colour quietly predicted the world we now live in. That is a genuinely cool way to have arrived at the grid.
Richter was refusing authorship. Not by making random marks, but by building a system strict enough that his taste could not get into it, and then letting the system decide. The painting is his and the colours are not.
4096 borrows that structure and swaps the system. Where Richter used arithmetic and slips of paper, this uses a market. Nobody picks the colours here either. They are produced by thousands of people trading, none of whom can see what they are painting.
Richter was the hand that held the brush while a system decided the colours. We are not even the hand. We wrote the math and then stepped back. The market is the brush, every trade is a stroke, and the people making those strokes cannot see the canvas they are painting. We do not get to choose the ending any more than you do. We built the instrument and let go of it, and that letting go is the whole point.
His painting resolved in a studio over weeks; this one resolves over years and might never resolve at all. His palette was complete by construction; this one is only as rich as the market that makes it. He knew what his painting looked like when he finished it. Nobody will know what this one looks like until it stops.
Richter described how he built the palette by repeated multiplication.
4 x 4 = 16 x 4 = 64 x 4 = 256 x 4 = 1024
He kept the image size, the square size and the number of squares in constant proportion.
That stepwise, multiply-by-four structure is the same shape our own tones sit on: sixteen gradations per channel, spaced so a difference near the bottom and a difference near the top feel like the same size of interval. He arrived at it with a pencil. We arrived at it because a market needs a scale that survives a token trading twice or two hundred times.
Richter thought 4,096 was probably too many. Past a thousand or so tones, he reasoned, the difference between one shade and the next stops being visible, and the extra precision buys nothing the eye can use.
That is true here as well. Sixteen tones per channel is a coarse instrument, and it is coarse on purpose. A pixel does not need to be uniquely identifiable. It needs to be somewhere in a field, and the field needs to hold together.
