Scrolling a dynamically created mc (rollover scrolling)

I’ve been trying to find a way to do this for a while…

Anyone have any good tutes, examples on creating the horizontal scrolling menu with dynamically attached clips? the style where if the user mouses over the right hand side of the menu it slides left, etc?

there’s lots of tutes out there for simple scrolling but not much that take a dynamically sized clip into consideration!

thanks for any input.
