I am talking about the opte project. For a brief introduction, visist http://opte.org/maps/
What this is: A map of the internet. No, really, it draws a node point for every host it detects and there from makes a web to near nodes. They even figured something to filter out local networks (since they have the same IPs over and over again). Now, you can see some major nodes which are the carriers that route the network traffic all over the world, most of them by some big providers such as Verizon and Telekom and stuff. Looking at this is pretty beatiful imo, especially since it features a 4000x4000 pixel map.
Moreover, it gives you a neat idea of how the internet is built and what it truly is. A masterwork of the humanity, one of the greatest things we ever accomplished.
