While you're waiting:
I'm a minimalist when it comes to screensavers. One of my favorites, Fliqlo, is a regular in the photos on unplggd.com (great site btw). Unfortunately, that particular saver is implemented in Flash, which I avoid on my MacBook Air for a variety of reasons I won't go into here.
Long story short, I've whipped up a similar (albeit simpler) screensaver in Objective-C, like the Almighty Steve intended, and, well, here it is. Simple. Beautiful. Seriously lightweight. Enjoy.
