Accordion covers (previously) are no longer just for soloists. You've probably seen five North Koreans performing A-Ha's "Take On Me." (Previously.) And of course tango is ever-popular for the accordion. But have you heard Bach's Toccata and Fugue in d minor? Or a medley from "The Sound of Music?" Or the first movement from Mozart's Eine Kleine Nachtmusik? Or a choreographed routine for North Korean school children? Or the theme from E.T.?
Take a game like Super Mario Bros. Introduce garbage data into the code, either through random Game Genie codes or a corruptor program. Try to play what results, while the laws of reality slowly go insane in the background, and upload the "best" results to YouTube. Can Mario make it to the princess when stomping a Goomba turns the air to water, when hitting a block ends the world, when the world is infinite length, if the ground can't support his weight, when touching a flagpole destroys his mind, when brought into being over an ocean immediately before a fatal heart attack, before the enemies turn into Bowser-halves, while the universe is freaking out around him? (hint: no)
