This is an android and ios app for "think with google" event in 2013, I designed all the app function and user interface, and I create a game for the event, people can scan the AR markers to get the medal, all the markers are google products and had been placed on the each booth, user need to visit through all the booths to get medals, then they will get a big gift aftet the event. when people scan the AR marker by their mobile phone , they will get some interesting 3D animations or some pictures or videoes. so they can get our concept when they play this game.
