wow, it somehow looks a lot better than previous GAN paintings I've seen. And there are weights of this network, shared by the author in twitter. https://mega.nz/#!TCgSVCTa!ZmcV381soxyqiQyHO4p60F5ogoHcaO1Pq...

StyleGAN2 takes 512 dimensional vector as an input. Would be neat to attach some physical input device, like a matrix of dials... And encode your own painting with it :)
