In a collaboration between PEER 1 Hosting, Steamclock Software, and Jeff Johnston, the Map of the Internet app provides a picture of what the physical Internet looks like.
I can’t say how accurate it is or if the described mechanisms are accurate, but it sure is fun to play with. The view above and a globe are placed a three-dimensional space, and you can zoom and rotate as you please. There’s also a time slider, so you can see changes to the Internet over the years.
Get it for free on iTunes.
