Make the page follow the mouse' X axis

Make the page follow the mouse' X axis

Hi I'm a total noob at jQuery and JS. <-- Just thought I'd set that out before continuing :P

I have a horizontal gallery, where the div technically goes off the page, it can be scrolled with the horizontal bar at the bottom. I'd really like it if when you begin to move the cursor to the right, the page begins to scroll along, and depending on how close to the right (or left) of the screen, depends on the speed and direction.

So basically, auto scrolling! :)

I've seen it before so I know it's possible... Has anyone got any ideas?
