Hi,
what about a map related with the internet infrastructure map ? With the important nodes and the main route used to connect the various part of the world.
Maybe it will be possible to group territory in groups by traffic type, like:
big site (google, yahoo, ebay, and so on)
gaming net (wow and similar)
p2p
and so on.
It will be fun to add spam, malware and viruses as well.
Just my 2c,
Nick
