After spending over 6 years, Kjetil Nordin has completed a crochet version of World 1 from Super Mario Bros. 3. It’s pretty insane, it’s just about 7 foot by 6 foot in dimensions, and it’s pretty detailed. It’s so detailed that when he noticed that the shade of blue he started the water with was wrong, he undid it all, adding an additional week to the process. Now that is dedication.
I think it’s pretty cool, he obviously can’t sell it, but he can make a few more of them and start up the entire game if he wanted. But at the current rate, according to reddit, it would take him between 45 and 130 years. Hopefully he has some other day job.
