This seems really cool and a way to try a bunch of looks you might not think of. Messed with it a bit and the results are pretty good!
I only have one comment/observation though. After rating the first generation, am I supposed to relaunch the executable file?
I don't think I should, as it generates a new generation 'map' but I don't see any other way of getting back to the generate appearances button after the rating screen.
Would appreciate some clarity on that particular step!
