Can Your iPhone Play the Trombone?

Or maybe this.



When the Saint's Come Marching Home...come on, that was geeky fun~! I guess our kids can truthfully say, "But , mom, I am practicing my music lessons" when they are messing with their iPhones. I am trying to think of applications that would make my life easier, but somehow I cannot imagine the phone sprouting arms and legs and scuttling around my house cleaning.

What app would make your life easier...or just plain fun?
