While doing my lightweight CMS research I sometimes get sidetracked by a fascinating link. Such a distraction is the css Zen Garden. It's the ultimate site skinning exercise: You get an HTML file—the same one used to create the home page— that you can't touch other than to link your CSS style sheet. Basically every major section has an ID so you can place things very precisely, pretty much anywhere you'd like. And some of the results are pretty amazing.
