Who said games aren't educational? It may not have the sex appeal of my personal time-merged favorite, The 1K Project II for Trackmania Sunrise, but the ensuing write-up, which helps explain quantum theories with a SNES classic gives it an intellectual bonus. The Super Mario World hack, by the way, is known as Kaizo Mario World and looks infinitely unenjoyable. What you're seeing above is 134 playthroughs of Kaizo layered upon each other using a custom SNES emulator.
