Musical Mario

I was reading about an IGN article titled '10 Wonders of the Gaming World' today and I have discovered something really neat. There is this special ROM-hack of the game Super Mario for the Super Nintendo.

It is a level where Mario makes his way to the end of the level of ememies, mushrooms and blocks. But what makes this level unique is that you don't need to use the controls to move Mario, as Yoshi, koopas, buttons, blocks and switches propell Mario through the stage for you (which is approximately 11 minutes long). As well as accomplishing this feat, it uses the sound effects of the switch- hits, coins, items and koompa shells to make a tune which is in perfect timing with the background music with not a beat missed.
