The evolution of books

With the first iPad applications hitting the market, it really looks like interactive books are about to enter the mainstream:

From what is presented in the video, I really like the graphical design and how motion of the reader device can manipulate graphical elements on screen. It looks like a well thought out concept and I am sure there will be much more inspiring interactive books appearing in the next months. In this regard, I don’t think Apple promised too much when they presented the iPad as a game changer for the publishing industry, despite what many critics are saying about apparent hardware limitations.
