The Marble Masks collection by artist Daniel Ochoa was created in 2022. He sourced 10 images from The Met NYC which are Public Domain Images. The artist wrote a script in python to generate 200 NFT's. Three features, Contour Layers, Reference Layers and Transparent Layers are randomly generated by a Chainlink VRF in the smart contract. These are passed to a python script which generates a final image with the use of openCV library.
