This is the hack I built for TechCrunch Disrupt. It allows you to create a presentation using photos loaded from Filepicker.io. You can then push that presentation to another browser that's at the unplugged.io website (such as one hooked up to a big projector screen).<p>Once the presentation is live on the big screen, you can control it from the iPad with multitouch gestures, and you can annotate it by drawing on the images.<p>The demo at Disrupt failed due to a screen resolution issue, but I wanted some people to see it actually working.<p>I'm using Firebase for all of the data storage and real-time features.
