Poker Face of Lady Gaga iphone performance by applegirl002 - my favorite and new internet and YouTube celeb

Korean YouTube user applegirl002 is now my favorite and new internet YouTube celeb.
She uses that Iphone app to create keyboard sounds and effects, but you need more iPhones in order to play different sounds.

she has 2 videos as of now, if you want to follow her, just visit http://www.youtube.com/user/applegirl002
she sings! she plays the keyboard and uses 4 iPhones. I can see the future that iPhones will be a perfect digital musical instrument.
