I'm trying to duplicate this effect from the Saints and Solidiers site

[size=1]I’m trying to duplicate this effect from the Saints and Solidiers site…[/size] [font=verdana, arial, helvetica][size=2][color=#800080]http://www.saintsandsoldiers.com/[/color]

The way that elements on the screen move left and right based on where the cursor is. In particular, the way that elements in the foreground move faster, and the background moves slower…creating a nice 3d effect.

How can I achieve this? Or could you point me in the right direction?

Thanks.[/size][/font]
