Urville

Gilles Trehin is an autistic [TC: Asperger's?] 28-year-old. Since the age of 12, he has been designing an imaginary city called Urville, named after the “Dumont d’Urville,” a French scientific base in Antarctica. He has created detailed historical, geographical, cultural, and economic descriptions of the city, as well as an absolutely extraordinary set of drawings. His Guidebook to Urville will be published later this year.

Here is the link, with images and video.  Here is more on Gilles, who I might add is cosmopolitan in his philosophical inclinations.
