This is a well done video about the decentralized architecture of the internet and exchange points. It’s kind of a video info-graphic.

I remember dreaming of animations like this while studying networking, algorithms and data structures. I hope one day there are graphics and animation libraries made to visualize program structures like this, so you could just insert some event sends to update the state of the visualization and it would take care of the rest. (i.e. pretty graphics, interpolation, etc…) There are so many chart and graph libraries out there, but it seems like the world of info-graphics could be so much richer.
