Push Pop Press is a new ebook platform that will change how people read and write books. With all the possibilities for multi-touch interactivity—infographics, audio, and video—writers will be able to deliver a more powerful and engaging message. The first ebook of this kind—designed for the iPad and iPhone—is Our Choice by Al Gore. I especially love the interactive windmill: you blow into your device’s microphone to make the windmill move. See a demo of the ebook on TED.com.
