In case you haven’t run into it, WorldMapper is an absolutely wonderful resource. It is, to quote the blurb, “a collection of world maps, where territories are re-sized on each map according to the subject of interest. 366 maps and PDF posters will be finished by February 2007.” – It’s a huge, and I mean huge eye opener.
Wander around. Look.
