Is this site complicated to navigate in?

Let’s say that you’re a business professional interested in seeing my work for a potential project…

www.design415.com

I am going to update the site anyway, but would like to know what areas need focusing on. My site follows the tradition of “create-your-own-interactive-environment” that a lot of designers do. Another tradition: Creating funky interfaces out of the current environment. The sign post in the train station doubles as a menu.

Thanks, and look forward to your valued critiques. Site has no sound, but that’s the least of my problems.
