Change the entire look and feel of your site with CSS
Dave Shea of Mezzoblue recently unveiled his CSS Zen Garden, intended to demonstrate how CSS can be used to present the same content in beautifully different ways. Dave was inspired by Chris Casciano's similarly experimental Daily CSS Fun and the recent Hack Hotbot contest. Currently, one or two of Dave's layouts display incorrectly in Safari, but they work perfectly just about everywhere else, and Safari workarounds are apparently in the works. [Zeldman]
The CSS Zen Garden rocks IMO!
