Author Here: Just wanted to share some technical details. The code can be found here https://github.com/valentinvieriu/stylegan2
The main code and modification were put together by https://github.com/pbaylies/stylegan2.
I've started with the pretrained ffhq model, and I've trained it using come hand picked 1000 images of cubist Wikiart paintings.
The frontend is Vuejs and it's using the amazing https://github.com/Akryum/vue-virtual-scroller for the very fast infinite scroll option. The app runs on Cloudflare Workers, using https://github.com/l5x/vue-ssr-cloudflare-workers-template
Hope you guys enjoy the experience and would love to get some constructive feedback
