This has to be one of the coolest things I’ve ever seen and it’s all a creation of a Hungarian university here in Cluj. The Facebook page for the people who made this can be found here.
What you’re looking at in the video is a visual representation (on a very small scale) of a sorting algorithm. This is the process by which computers organize (sort) data, a vital component in many, many things, including how Google fetches all those results for you every time you perform a query.
Awesome stuff! :)
