http://www.sanbase.com/ - these were created long before AI became a household name. Actually no AI involved at all. All just pure math. Think it is called "generative art" or something to that tune
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)...
"Site broke on me" - interesting I did not notice anything. Maybe because we might've used different browsers
