You come across some interesting things on the net from time to time, don't you? How's about this for a fantasy setting - The Map of Humanity:
I highly recommend you click on it and have a zoom around. Eurocentric, perhaps, but nevertheless an item of crazed genius. I don't quite know what to make of it other than that - other than to say I'm going to straight away put it in my file of "Setting ideas that are just too difficult to envisage pulling off, but which I take out from time to time and gaze at mutely."
(That file also included my abortive attempt to turn Borges' Celestial Emporium of Benevolent Recognition into a campaign setting - more on which I think I'll write at a later date.)
