I have always been fascinated how people come up with good visual ways of explaining complex things, this video is one such appreciative work on explanation of quicksort algorithm (link got from blog of my friend Santhosh Ahuja). Being in the software field and involved heavily in recruitment of people at various levels, what I have learnt is it's easier to find people with sound knowledge but difficult to see them possess the art of explaining things effectively (which unfortunately is a key trait needed in a personnel not only in the software field but in other fields as well).
