Ming + PHP5 + AI = Pretty
cyberscribe writes "Project K++ just released its first alpha version today. The project aims to explore computer-generated abstract art using PHP and Ming. The name of the project is an homage to Wassily Kandinsky, father of abstract art. Caution: the Flash movies can be intensive on your graphics card. Other caution: hitting reload to see the next cool computer-generated abstract 'painting' can be highly addictive."
Evolvotron
From the page: Evolvotron is an interactive "generative art" application for Linux to evolve images/textures/patterns/animations through an iterative process of random mutation and user-selection driven evolution. It's not running in Flash, you may render all images to arbitrary resolutions and is perfect for creating new desktop backgrounds... Also check the Gallery and Animations.
The code is licensed under the GPL. It uses Qt and is multi-threaded.
This k++ (or whatever) is an ok example, but there are some truly fantastic sites around..Try Pray Station or (one of my hero's) John Maeda. John's work is incredibly beautiful, and he's a half decent coder to boot.
