It’s pretty simple and straightforward… so it’s pretty much a winner for me. I’m looking at it with a PC running Windows 98/IE 6. I’m not sure what exactly you expected it to look like, but it looks fine on this end.
There are a couple of small things though: the font looks a little blurry. The text is still readable, but the blur looks a little unclean… inconsistent with the clean horizontal lines. Also, it was pretty unclear that I should hit the logo to return to the main page. I stumbled upon it by chance. Also, increase the hit area of the main page button - it’s a little easy to miss it when I have my mouse in the blank areas in the center of the logo.
Other than that, It looks great. The intersection tweens are interesting yet simple enough and I like that you have a wide range of colors while maintaining a simple site.
