Inspired by the Million Dollar Homepage, we set out to build an immutable version. The 21MMpixels contract is our vision in action. Each owner has complete control within their 2,500 pixel, 10,000 pixel or 40,000 pixel tile with an immutable record of 60 bytes, and the ability to update its URL. 21MMpixels ensures that your piece of history is never part of a decaying digital artifact. You control your portion of the 21 million pixels image every time you set your tile image.

8,400 original 2,500 pixel tiles. Every tile is a unique permanent part of the 21 million pixel image. The location of each tile within the 6000 x 3500 pixel image is defined in the contract, and not subject to mysterious metadata files.

Set your tile image at any time. Helper functions in the contract make storing and retrieving IPFS hashes, Arweave Tx Id's and Base64URLs simple.

Collect and merge four adjacent tiles to create a 10,000 pixel big tile. Merge four big tiles to create a 40,000 pixel super tile.
