generative art is of a completely different tune...
even if for this style they might not be that different results, the neural net(s) here (the "AI") can have details and textures simple math cannot, such as I saw a horse head in one, some other things in others...
but it's still very cool, even if the site may or may not be slightly deteriorating (top banner's broke for me, wouldn't be surprised if some other stuff was too)...
I myself did procedural texture generation at one point. There are also commercial packages. This was long time ago so I am not sure in what state those commercial offerings are now. Still you'd be amazed what kinds of textures can be generated procedurally. Definitely not anything less the AI can come up with. At least from what I saw on that AI site.
"Site broke on me" - interesting I did not notice anything. Maybe because we might've used different browsers
but it's still very cool, even if the site may or may not be slightly deteriorating (top banner's broke for me, wouldn't be surprised if some other stuff was too)...
