Push Pop Press is a new digital publishing platform that's attempting to redefine the way we publish and experience books. Quite a bold ambition for a small startup. Judging by their first publication however — Al Gore's "Our Choice" — I think they've built the best platform of its kind to date. Never has an interactive book felt this intuitive, fun and user friendly. UI Designer Mike Matas explained the platform in a little more detail in a recent TED talk. Lest not forget that they've done a damn fine job with the website as well.
