Hmm, I don’t think so (though I’ve now learned what a parallax effect is, so thanks for that new term).
I don’t want the content to appear to slide up the screen — I think the effect I’m after is more like a slider, where clicking on the option you want on the sidebar (“2010 Awards”) causes the content you want (the 2010 awards recipients) to simply appear in the right-hand main content area, without changing the URL of the page you’re on.
