I just found this by random and it’s well worth a look if you like whacky artwork and clever computery stuff. Essentially it’s a big Flash animation, but it’s very hypnotic. A series of images by various artists have been layered together. As you dive into one you move to the next and so on.
It’s also available as a downloadable screensaver, I think just for Windows.
