This is really interesting and fun! One bit of UX feedback - I played about with children, cross breeding and editing genes and never figured out a mental model for what interactions caused a derivative image to be previewed vs being used to update the current seed image. Clicking on images often saved them, though I'm not sure what that means for me, the user. Do I need to save a child image in order to derive from it? Even if it's just an intermediate result I want to play with? When I breed images, I see the image on the left is updated, but it doesn't seem to update the seed image being used in the 'Children' tab, or the genes available for editting? I ended up saving and then re-opening images as a relatively safe workflow, but it would have been a lot clearer if there was more UI feedback showing me what's a preview and what's an input at any point. All those questions were rhetorical btw, just talking through my user experience :)
