There are some great visualisations here. Coming up with good visualisations is tricky. I can't help but mention my own attempt at a more general framework for algorithm visualisation: http://will.thimbleby.net/algorithms/

Beautifully done! I wanted to build something like this for so long. No more ...! :-) (It's already there now.)

Edit: And why doesn't Google find the good stuff when I am looking for it ...?! :-)
