You're out enjoying a quick walk through the city. Suddenly, a small but friendly looking pigeon swoops out of the sky and circles around your head, indicating that he has an important message to deliver. You quickly hold out your hand and the pigeon flaps to a stop in your palm, ready to deliver his message. You pull out your device and swipe it across the pigeon's chest, downloading the message to your device. You thank the pigeon, who flies back up into the sky, and proceed to read the important new message on your phone.
