In celebration of International Peace Day 2016, Google's Android Team has partnered up with development team Active Theory to launch an app called Paper Planes which was previewed during Google I/O this year. The app essentially lets you launch a paper plane from the digital space on your smartphone screen out into the world, allowing it to be caught by someone else around the globe on their own device. With the app, which Google states is available through Google Play but also as an Android Experiment, users can fold up their own paper plane and then launch it outward by using a throwing gesture, but not before adding a stamp with their location. As an added bonus, users will be able to see their plane flying into the screen after being thrown if they visit the desktop website prior to tossing the plane.
As planes are tossed out others can pick them up, add their own stamp, and then toss them back out with the rest of the planes where they'll continue flying around until someone picks them up again. The more people that grab a plane, the more stamps that get added to it which gives users the opportunity to check out where their planes have been picked up. For example, a user could toss their plane out into the world and then come back to it a few days later, use a gesture like they're catching something with a net to grab their plane, and then view every place it's been thanks to the added stamps where it's been picked up by others.
