This project was 100% coded by GPT-4. It allows users to mint 10x10 pixel art NFTs with a maximum supply of 420. The contract includes a function to initialize the pixel art data and colors for the NFTs. The contract generates SVG images for the NFTs and includes a tokenURI function to retrieve the metadata for each NFT. The contract also uses bit-packing to store the pixel art data more efficiently. The reason for choosing a mint price of 0.0069 ETH is that it is a cheap price but also has meme potential due to the cultural significance of the number "69". -- Note: this description was also generated by GPT-4.
