Visualising sorting algorithms

Insertion, Selection, Bubble, Shell, Merge, Heap, Quick and Quick3 sort compared and visualized.

Inspired by recent videos that visualized various sorting algorithms w/audio, I decided to create a Radix sort video using using Python:

(YouTube link, although video is laggy so I recommend the previous link): http://www.youtube.com/watch?v=nJ8QKkei7QY)

One of my favorites is merge sort, visualised in Protovis:
