Please help! infinite menu to make panoramic scene

hey guys!

im trying to use the “infinite menu” tutorial on kirupa’s site to make a panoramic scene.

I would like to make buttons that appear as a foreground that would move faster on scroll (and stop on certain points), and would like to make buttons that appear as the background move slower and at a shorter distance (also stop on certain points) on scroll.

im trying to create something like this:

except very simplified only using a few buttons.

any help or links to tutorials would be greatly appreciated as i am on a tight deadline:ne:

thanks in advance!!
