Vertical scroller - automatic

I have recently come across a vertical scroller on this web page:

http://shop.tokyocube.com/toys.htm

I would like something similar but i have searched the forums here and, of course, google but cannot find any tutorials that match my requirements.

Does anyone know of a method of how to do this (preferrably using actionscript) OR any tutorials that can help me with the development of this?

Thanks in advance
