Some Delightful Android Phone Apps

So Catherine got an Android Phone recently.  Today, she found some "talking" apps for it (from http://outfit7.com/), which play back anything you record into them, but with the spectrum modified.  The little animated characters in the apps move and sing the modified recording back to you.  So: A quick tour of 20th century aesthetics!  Sprechstimme from Pierrot Lunaire (Schoenberg); Percussion Music (Varese, Cage); the Dies Irae (quoted by just about everyone, but most recently (to my knowledge) used by Kenneth Gaburo as the theme to his 1987 Mangrove); the Ursonate (Schwitters); and Extended Vocal Techniques (as used by so many of us).  And all this in 1 minute!  Enjoy.
