This one is interesting because it's the internet from about 12 years ago. I'm guessing that it would be almost impossible to make an image like this now because everything would be a stream of light.
This one is also pretty neat-- it reminds me of what Frankie and I were talking about when we said that the internet should almost be visualized like an atom.
This is cool-looking, but kind of a generic, visualization of the internet. I tagged it though because it looks remarkably like mapped-out neural pathways (the brain of the machine...?).
