JQuery plugin to animate overlay

Question

I'm looking for a JQuery plugin to animate the appearance and disappearance of an overlay div. Something like what Rackspace has here:

http://www.rackspacecloud.com/

After staring at the page for 30 seconds or so, a div comes sliding down from the top asking you whether you want to chat with a rep. If you ignore the div for a period of time it slides back up.

I know I could hand code all this using timers and animate() and such, but hoping someone has done it for us already.

Any ideas?

Ok Will is correct. animate() is more powerful than I had realized. I was able to get it doing most of what I want with 4 lines of code:

setTimeout(function() {
  $j("#survey").show();
  $j("#survey").animate({top: "300px"}, 2000);
}, 10000);
