There are those with free time, and then there's Joseph Braybrook. This fine bloke managed to recreate some 86,000 square miles of Great Britain within the Minecraft universe, and moreover, it took but a fortnight to concoct. Further justifying his work as more than goofing off, he used Ordnance Survey terrain data in the world's construction, leading Graham Dunlop, OS Innovation Lab Manager, to proclaim the following: "We think we may have created the largest Minecraft world ever built based on real-world data." The new universe contains over 22 billion Minecraft blocks, and once players have downloaded the 3.6GB file, they're free to build at will. Just don't go planting any US flags -- that's just downright rude.
