Natural Sliding?

Hello, I have a small box(graphic) on my stage that contains a video clip. As the .swf is played this box slides into the stage area using a simple motion tween. The tween works, but it’s very crude looking. Is there a script or method to make this box that slides into my stage area have a more natural look. Maybe something with friction(box slows down the futher it comes out) or something along those lines. I noticed on the Dope Awards site, when the menu first comes in it has the effect that I am trying to create, it’s very natural looking. Any feedback or suggestions would be great. thanks ian
