What surface to use for a scrolling parallax interface with Famo.us -

i create interface based on 3 layers stacked produce horizontal scrolling parallax on user input (on swipe). each layer got image placed randomly.

should utilize scrollingsurface (that allow 300% of screen width ) or simple surface layer ? (or more clever option)

the solution used create surfaces same 'index' , programatically create parallax effect based on touchsync
