The Super Mario Bros. Audiosound Super-Synthesizer

Okay, unfortunately, it isn’t quite as cool as the name makes it out to be, but this should be good for at least 10 minutes of clicking and chuckling. You can load four different world themes, then whack away at the various icons to make their sounds. Ultimately, the net result is that you get the sound from the game without actually playing the game. I’d say that it’s probably more entertaining to just play the game in the first place.

Now, if someone made a SWF interface for the music creator portion of Super Mario Paint, _that_ would be fun.
