Any Tutorials to build a simple site like this?

Hi - I have been noticing quite a few nice sites using this scrolling effect in HTML recently. As I use flash - I have not really stuck my nose into javascript. However, the way this site uses JS (at least I think it does!) I think has so many practical advantages to my tricks in Flash. See the site below: And does anyone know if there are any tutorials out there to learn how to put it together? It’s just an expanding menu - but makes things so Clean!
Help/pointers would be most appreciated :slight_smile:
