Visually it's great, however, show this website to Jakob Nielsen (usability guru, search google), he'll point 1000 usability flaws. IMO being a graphic and multimedia designer, I think that the site is very "original", however, when people search for a webpage they are looking for information, simple as that, and this site does not make information the main subject, the true webdesigner challenge is to make a visually great website (which runs on 1024x768 or lower) without compromising the access to information, simple and straight forward.. and from that point of view, this site lacks some "easyness".
But's that just me.
the problem with this site is that you spend too much time reading things and not enough time looking at things. the actual work is buried in the references section with a confusing interface.
I guess that good design must have a function, and a visually good site doesn't make it a good one, take the www.apple.com website, it's very eye pleasing and usable, what I'm trying to say is that complicated isn't always the answer. Simple and efective, pleasing to most users, this has to be the designer's goal.
You can't agree with everything that Jakob says, however, it was he that implemented most usability functions that you see in Flash, so, give the man some credit.
