Absolutely brilliant series of videos interpreting the various sorting algorithms using folk dance. Nice touch on the conventions for comparisons. The videos have no voice-over or distracting subtitles and are slow enough that you can show the video and comment on each of the steps in the algorithm while it is occurring. After a few steps, have students predict what will happen next (e.g. who will dance next and who will swap places).
You can find all of them at the AlgoRythmics YouTube channel. I'm hoping they find a way to get more of the popular sorting algorithms done.
