Just been catching up on Smashing Magazine's latest email and saw this project that has generated a bunch of rights free faces for non-commercial use.
I often just look in social pages in regional magazines to find persona faces, but this looks like an interesting place to gather them.
I am most interested in how they came up with the idea to create this service.
They also term this kind of AI and ML pipeline for content generative media. We used to have User Generated Content (UGC) now we have another term for programmatically generated content
