Here is a unique Dark theme I call Deep Space [1]. It is XHTML/CSS valid (like every other design I make) and it is a 2-column layout.

The only problem is that IE6 is REALLY bad at rendering images (among other things...) so the page slows down on IE browsers...

Enjoy the stars, and if you want - you can even right-click on the "stars.gif" image and set it to your desktop wallpaper! Have fun.
