What happens when you take 800 hours and a Super Mario Bros fan who knows how to crochet? An enlarged "World 1" map from Super Mario World 3 -- made entirely of yarn. Kjetil Nordin from Denmark has spent the last 6.5 years crocheting this map that is insanely true to the original. Just don't ask him when he's going to finish "World 2"...
