I have tried a number of different things, including selling individual artworks, licensing, commercial projects, and NFTs.
By far NFTs have been my bread and butter. Cringe, I know. But past all of the scams, grifters, and bullshit, there are actually collectors and artists doing amazing and innovative work with code-based art. A lot (but not all) of the bad vibes have found something new to flip a quick buck on, and what's left are passionate folks. Not to mention places like Sothebys, MoMA, Christies, etc.
Why does generative art marry up with the blockchain? Because you can store code on-chain, and you can use the transaction hash to seed a PRNG. This allows the artist to issue a set of unique artworks all generated from the same algorithm.
To see what I mean, check out www.artblocks.io and fxhash.xyz.
I like your art but how do you make money with it?
