Map of the Internet
Jay Simons has produced a fantastic map of the internet. 
"This poster includes one full map of the internet, 4 minimaps showcasing NSA surveillance, most used social networks, most used internet browser, and worldwide internet penetration, list of Alexa Top 500 websites, quick timeline of the Internet History, top software companies and much more!
A lot of this is based on the ideas from xkcd.com that have been produced over the years.

I love the detail of the new map as you zoom in and explore  and there are some good jokes to look out for.
