The Brisbane Google Student Ambassadors put on an event called Appify with Google! The main point of the event was to get people to collaborate to create apps together and apply for the Admob Student Challenge.
The whole event went for 4 hours! We had over 70 people in attendance of whom we split up into 5 or so groups and we helped them to flesh out a single app idea that they could work towards. They came up with some really fantastic ideas. Then we had a few presentations and questions.
