Cool Screensaver Recommendations?
 

I know a few good wallpaper sites for finding cool shit, but never seem to have any luck looking for good free screensavers.

Anybody know where to get some cool ones? Especially anything that takes advantage of 3d hardware.

You can kill two birds with one stone: http://www.grid.org/projects/cancer/

Its a 3d screensaver that uses your spare cpu cycles to do cancer research.

That's a pretty cool program.

Sleep mode... save your electricity bill..

Nobody else got any cool ones?
