See Game of Thrones’ Westeros Re-created in Minecraft
Will Blew and Jacob Granberry are the guys behind WesterosCraft, a site devoted to "recreating George R.R. Martin's universe, brick by brick. Both were fans of the novels and inspired by other Minecraft players who had built 1:1 versions of Hogwarts and Middle-earth." And, hey, while you're at it, watch a new featurette about the art direction in season three.
