I suspect you will like AR Zone. It's cute! Open AR Zone. Choose AR Doodle and grab your S-pen. You will be drawing on what the camera sees. As you pan, what you drew stays in the sky or around your face, depending on camera direction. Turn the camera around and scan the room per the instructions. Then start drawing. You can record while that happens, and start SmartView (via pull down menu) to cast that to a big screen TV. There is WiFi lag, but it is still very cool. That's just one part of one app, too!
Try FX Guru for free shits n' giggles by superimposing silly gifs over what you are recording. Like, dropping a satellite on a house, or dancing reindeer in the room you are in..
Enjoy. It is great device!
No, "guru" like in a mobile video effect application which has this effect.
In case anyone is curious, the app he used for the cake girl is FxGuru.
My guess is FXGuru or Action Movie FX
FX Guru is decent.
