Page widget or plugin that does the 'Recent Activity' effect on foursquare.com?

Question

I like the 'Recent Activity' effect on http://foursquare.com/. The top activity pushing all beneath. Is there a JQuery plugin or widget I can readily use which does the same?

(I am a lazy developer so please no 'you can develop this yourself' responses)

Answer 1

jQuery Spy is what you're looking for.

Answer 2

That can be achieved using the default jQuery slide() function, what happens is that the new item on the list comes with a slide (show) and the last one with a slide (hide) in it.
