I love the way this site does transition between pages.
Is the content being loaded via AJAX or is the browser actually opening the different pages when you click on the sections?
Because the links are being changed in the URL, how is it that they are maintaining transition between the sections ?
jQuery.address is being used for URL management and custom transitions for page change effects. (See http://digitalroadmap.com/js/functions.js
line 19and below.)
