Via Metafilter comes this awesome little documentary about a man, whose hobby for the past four decades+ has been painting an increasingly-elaborate map of an imaginary city and its environs. The best part is that he uses a deck of cards to procedurally determine which parts of the map get redrawn, transformed, updated, destroyed, and rebuilt from day to day, and so this fictional world has been evolved over the years, with careful historical archives kept. Effin’ brilliant.
