How does the Facebook app "Take this lollipop" work?

[Alex]

I just did the facebook app Take This Lollipop, and I really want to know how it works. I realize that you gave it permission to access your info so it can get pics and stuff, but how does it actually show it on the video? Does anyone know?

Thanks
