I'd like to introduce you to a neat iPad app that was created by one of my training clients...Lerner Books. After just a couple of hours of training and a bit of guidance along the way, one of their top designers was able to convert their Journey into the Deep print title into a really great looking iPad app using Adobe InDesign CS5 and the Adobe Digital Publishing Suite.
The designer did a great job on this book. The photography is gorgeous, she added some nice navigational and interactive elements, and included some bonus video elements as well. The vertical navigation within each chapter reinforces the idea of "diving" into the ocean depths
