That's a pretty interesting way of visualizing it, best I've seen. Some others... http://www.sorting-algorithms.com http://www.sorting-algorithms.com (Interesting animations of all the major sorting algorithms). Although my all time favourite is GDB + GnuPlot + 3d Array (array index/values/step) plot and stepping through the steps of the sorting algorithm.
