Well, you will probably not be able to see it at the picture, but every stop at this underground network is another major city or caplital of the world. I use to have a look at it every now and then to remind me of the fact that all those wonderful friends I have all over the world are never further away than a phone or a computer or a few stops away at the global underground. We are all connected and if you are really close you are never very far away.
