Over the past few weeks, I’ve found some cool screen savers for Windows XP (well, for any Win32 system, really). Actually, I was searching for how to write my own screen saver, and I found a page full of screen savers. I particularly liked TwinkleGL, Rotating Galaxies, and ZoneRings.
Then a few days ago, I ran across references to ZMatrix and Drempels over on Matt’s site. These two are more than just screen savers — they can also give you an animated desktop background. Coooool. I’m running Drempels as my background, and ZMatrix as my screen saver.
