First of all, let me tell you about CSS Zen Garden. It's a global community effort to showcase the power of design by CSS (Cascading StyleSheet). The HTML (XTML Strict for HTML-non-novice) is the same for everybody but every person who choose to do a design gets to define their own stylsheet. This is a wonderful addition to the whole Web Standards movement where the principle is simple: HTML for content, CSS for layout and design.
Now, this zengarden instance called Geocities 1996 by Bruce Lawson. You can read more about the design on his site. Bruce claims to get his inspiration from this site but I suspect that that site, like Bruce's, is a joke.
