Twenty five by twenty five. Five blocks of five, with a centre pixel.
The bigger sibling of ELEVEN. Same idea, more room: your pixels go into the contract itself, not a link to a server that can go dark.
25 is odd on both sides, so the centre is a pixel rather than a seam and mirroring lands on something real. It divides into five blocks of five, which is why the grid guides sit where they do.
Draw, mint, and the artwork is stored whole on Tezos as vector. Take this site down tomorrow and every piece still renders.
We charge nothing. You pay only Tezos storage, once, and the pixels stay in the contract forever.
Open any piece, change it, and mint your version. The chain records what it came from, so the whole line stays visible.
Your pixels are inside the contract now. No link to break, no server to lose. Take this site down and it still renders.
