Air Writing - New app for cell phones

[homebase]

It still seems strange to me to be somewhere like an airport and see all these people fast walking and talking and no one is with them. Texting doesn't seem as strange as some one using hand gestures and talking into air. Now they have developed "air writing" where you can point your cell into the air, write something out and send.

I wonder what that will look like at an airport?
