Flashlevel Nav?

I don’t post to many things I can’t find the answer to myself but this one I’m having a few problems accomplishing.

I want to create something very similar to the flashlevel (http://www.flashlevel.com) navigation they have, JUST the navigation. I would like to turn it into a thumb scroller. It’s very similar to an infinite menu, but not infinite.

Just thought I’d see if anyone can help me out w/ it as I’m no flash guru. Any help is appriciated.

Edit:
Oh yea I want to be able to upload my images dynamically, using an xml list or something too… but that I can establish later.
