I find this screensaver to be a _revelation_. I have an iMac G5, and the minimalist beauty of Cavendish is a perfect complement to my calmly designed, beautiful new machine. I am in love with this huge menu of settings, and the fact that the screensaver can be set anywhere from a placid, idly rotating pattern, to a more intense one that makes the processor fan come on, to one that is so incredibly powerful that it basically makes the System Preferences choke...universes colliding! I am the Kreator! Maybe some of the reviewers want patterns of poorly-drawn crap (toasters, anyone?) floating around their screens, but not I. This saver is perfection. Seven thumbs up.
