Norwegian computer programmer and skydiving champion Kjetil Nordin put over 800 hours of work into researching and crocheting this lovely recreation of the map for Super Mario Bros. 3 World 1. Redditor Buttermynuts spent several minutes making it into this equally lovely GIF.
Anyone with basic crochet skills and a whole lot of free time can make a map out of yarn, but Nordin went several extra kilometres, researching the exact yarn colours needed to emulate the map -- which Reddit points out seems to be for the Super Mario All-Stars version of the game -- going as far as to scrap an entire section and restart when the water turned out a bit too purple, as reported by NRK (via IGN).
Redditor AlexKingshill, posting as a friend of the creator, uploaded a slew of lovely shots of the gorgeous piece.
Nordin's next project will be finding a way to mount the yarn map to a wall without completely ruining it. I sincerely hope he does not own cats.
