It’s generative in the sense that it’s how Nouns Builder NFTs work. Purple has a single image a single layer but it randomly selects an image for every layer you give it. ie if we had 10 background colors, 10 images and 10 paint drip marks every new nft would be some random combo of the 3 layers.
Oh, nice. What if I make that paintdrop mark a poem? So we have some sort of base layer x10, an oberlay image x 10 and 10 poems?
