Anyway to make Scrollable Content II go side to side instead of up and down?

I'm looking for a scroll box that goes left to right, rather than up and down.

The script I like is http://www.dynamicdrive.com/dynamicindex11/scrollc2.htm - mostly because I can customize the arrows, and it keeps the whole thing fairly unobtrusive on the page.

I feel it should be easy to change the direction, however I'm no code guru, and messing around with it might take longer than I've got.

Any quick and easy suggestions for me? (Another similar script would be just fine as well!)

Thanks in advance!
