I saw this great image at Jeneane Sessum's blog and thought it was a wonderful album cover (oops, still thinking in LP mode).
Then I found out that it was generated (click-through on the picture) at Levitated using Flash. Cool! Then I clicked on a link and found myself with a page full of Flash-based open source computational animations and interactive paintings. They are perfect for creating eye-candy banners for geeky websites. A Must See!
