Annoying sideways slider effect

[H4T]

A client wants me to incorporate this effect which I find terribly annoying, but he wants nonetheless.

Click any link on the gray menu bar, and the content pane will slide to the next 'page'. I think this particular one is done using MooTools, but does anyone know where I can get a ready made script for this? I don't have the time to spend coding this stupid effect from scratch for the amount of money he's paying me.

panic.com/coda

he didnt even change the name of the javascript file. So I dunno...
