It took me some time to figure out how to go back to main page...
When I tried to browse 01. web page from work history page, it overlays on top of the page. Not really a great experience.
Creative initiative :) Even if it's a bit hard to browse, I like the way you tried to re-invent navigation :)
Unfortunately, at this moment, the site is buggy (each part overlays on top of each others to a point that it's not usable) :(
