Well, in Google Chrome, at least, the links go to white-on-white on hover -- that's probably not the effect you wanted. I can't find the sub_floor page -- you have to keep in mind that the file system on Linux is case-sensitive, so it may be a misplaced capital letter (or even just a misspelling), so check your filenames carefully. It took a while for me to figure out that the script text was the current page indicator -- it looked rather like the left-hand navigation didn't finish loading. I'd suggest either extending the black background all the way down the left-hand side of the page or finding a different way to indicate the current page.
The design, as a whole, actually isn't too bad at all, but those two usability hiccups really detract from the overall impression. Fix them (and that doesn't take a lot) and the whole gestalt of the site changes for the better.
