A tribute to the "One million dollar homepage". You can buy ads (pixels) in the grid with Ethereum. The pixels are relatively cheap and limited. You can sell your bought ad at the marketplace for a value of your choosing. If the grid is sold out, the prices will rise! Profit! This is an open source project. It makes use for several libraries and frameworks such as Truffle, Web3 and IPFS. The smart contract and source code link are embedded on the page.
