It looks snazzy, but the example does a brilliant job of defeating the object. It works with flipping pages to see more content, but then you have overflowing content on one page that requires vertical scrolling* to see it all.

I've never come across a book that requires me to do something other than turn the page to read more.

*This is also broken (presumably in an attempt to prevent scrollbars appearing), and requires a click and drag to work normally.
