This is a video of several Super Mario levels being played on a city sidewalk. Except they weren't actually played on the sidewalk, the video was motion-tracked and then the Mario levels were superimposed to appear as if they were played on the sidewalk. Which, I bet if you asked Shigeru Miyamoto, is the way the game was meant to be played. Ooooor projected onto a bath-towel while you sit on the shitter. Which, no lie, is exactly how I beat Ocarina of Time.
Hit it for the video.
Thanks to Christian, who once played Kid Icarus on the side of skyscraper until a bird shat in his hair.
