This 6 minute clip showing the visualization and “audibilization” of sorting algorithms is so mesmerising (and a great way to grasp how sorting algorithms work):

The algorithms are: selection sort, insertion sort, quick sort, merge sort, heap sort, radix sort (LSD), radix sort (MSD), std::sort (intro sort), std::stable_sort (adaptive merge sort), shell sort, bubble sort, cocktail shaker sort, gnome sort, bitonic sort and 30 seconds of bogo sort.

Thanks to Matt for pointing this out to me!
