Have you heard of Push Pop Press?

Push Pop Press is creating a new breed of digital books by bringing together great content and beautiful software. These books let you explore photos, videos, music, maps, and interactive graphics, all through a new physics-based multi-touch user interface.

They recently shared a sneak peek at their app, with co-founder and former Apple designer Mike Matas showing off an interactive iOS version of Al Gore’s book Our Choice. Confused about what their app could bring to the book? Here are a few examples: there’s about an hour and a half of video content, 20 interactive infographics, and all photos can be plotted on a map so the reader knows precisely where it was taken, and Gore narrates parts of the book.

Mashable states that, "The interface goes far beyond what one would find with Kindle or iBooks. The entire screen is occupied by content, and multimedia items can literally be lifted off the page using finger gestures. You can also pinch and zoom on just about any piece of content, and you can move through the book’s various chapters using your finger to scroll."
