I had 8 minutes to demo Discovering Emotions with Zeely to the audience. It went by fast but I managed to give a walk through the app in just under 8 minutes. I had the iPad connected directly to the projector and seeing the app projected on the wall was quite the experience.
Here is the setup. I am very comfortable delivering presentations and training to audiences however playing the app while explaining what is going on was challenging.
