The best part of YouTube user ConnorRWilson's faithful stop motion reproduction of World 1-1 from the Super Mario Bros. isn't that it's made from paper. Or that they even animated the flashing version of Mario when he's invincible.
No, it's the fact that nailing the top of the flagpole at the end of the level is still damn near impossible even when you have complete control over the situation when you're animating it by hand. So we're happy to overlook the small discrepancies like Mario breaking a block when he's small, or killing two Goombas with one question block jump. Bravo, Mr. Wilson. [Gamma Squad via Geekosystem]
