I am trying to replicate this functionality on my website - IRRLAND.

I am really not having any luck and not sure where to go. so far I have got the jquery ui draggable working on the background.

I have no idea how i would go about allowing the user to drag the image to the right and get to x point and if the image is finished snap back to the edge of the image on the right with some kind of easing. I guess looking at the example will be the best explanation of what i would like to create.

help would be very much appreciated

thanks in advance
