There is nothing that can match the thrill of being able to turn into a Unicorn and then catch donuts falling from the sky. This is precisely the reason why we are so much in awe of the game Donut Horns. This game was created by B-Reel using the Google+ Hangout API+
API enables everyone to customize intimacy and participative spontaneity of Google Hangouts like Name tags, Custom hats, and Glasses. You can control the app with your body, have custom media effects, play games, and above all else collaborate with others in real time.
This is not a very complicated procedure but in fact is pretty easy. The Google+ Hangout button can be installed on your site and you can launch it with your app preloaded. There are several, 200 to be precise, apps created thus far. From fun ones like the reality show trivia game which BRAVO created to useful ones like Lower Third which enables participants to have newscaster like nameplates. There is also a directory that some Google+ians have created to view the different Hangouts that are present.
Apps have increased the popularity of Hangouts. Today one in three Hangouts uses apps. It is also proven that Hangout duration has gone up considerably when apps are used.
