I hadn't seen the Atlas Of True Names before but was rather taken with it when I came across it this morning. Cartographers Stephan Hormes and Silke Peust have created a series of maps that feature the etymological roots (or original meanings) of places and references of countries across the world. The detail above is taken from a map of the 'Great Land Of The Tattoed' (Great Britain). They've just released an updated version of the USA and there's an interactive map of it below. Lots of fun.
