You could always make an animated Gif or small AVI yourself. There's plenty of freeware or shareware tools out there.
Here's where I got mine from : http://www.snapfiles.com/freeware/gmm/fwani.html
I think it's called Unfreez. (Named so just to wind Hitcher up!!)
Word of advice though - if you're going to download any free software I suggest that you run a Spyware programme straight afterwards, as very little is ever really free on the interweb, and this site installs web browsing trackers on your PC if you download from them.
