I sort of like the graffiti-style you've incorporated here, though from a usability perspective I'm not exactly sure what I am looking at. Also, the logo/image in the background on the upper-left hand corner is being partially obscured by the right aligned div when I reduce the size of my FireFox window. I'm running 2.0.0.7 on a Mac. Hope that helps!
The intro page looks fantastic!, maby a better navigation on another spot of the page will do miracles.
