Phill Ryu is making us Windows users jealous (again) with his list of the Top Ten OS X Screensavers. With one $20 shareware exception, all of his picks are free, and all of them are universal binaries and look stunning. I'm particularly intrigued by the Simpsons-inspired Mr. Sparkle screensaver at #9, Hills at #3, and Fenêtres Volantes, which turns your windows into floating, drifting 3D objects, at #1. Ryu also names a handful of promising runners-up.
