Dynamic text 'easing'

i would really like to learn how to make scrollable text ‘ease’ up and down. an example would be the news section of the 2210 media site (http://www.2210media.com/main/flash.html). if anyone could point me in the direction of a tutorial, that would be great. also, would it require a special text scroller to be created? just curious…

thanks!
