You could always write this yourself with jQuery. Obviously your into web design/dev so you may want to grab a browser extension like Firebug. If you ever find something that you’re curious about, you can use it to view the source code for just about anything (aside from server-side). You can even view the source for that exact page. In their ‘script.js’ file the author, Dominic Whittle, has done a pretty good job of documenting his code as well.
Gotta love this comment.
