Javascript's onscroll event is a wonderful tool. It's one of the best ways to leverage an extremely common and expected interaction pattern (scrolling down a web page) to do interesting and unexpected things. I used it to create a sort of paginated-persistent-bookmark navigation for my new portfolio site earlier this year (in profile, if you're curious).
Yeah, Chrome doesn't like this site. Which is a shame - when I opened it in Firefox I was impressed, but if I had not been prompted to check it out by the comments on this thread I would have moved on...
This website http://www.hellokeepa.com is also doing some interesting things with what looks to be the onscroll event, the page continuously wraps around. Also notice how you can drag the page left and right.
