Very cool. A few weeks ago my friends and I put together something like this using google docs for a friend's 30th birthday and had it printed. This would have been perfect!

A few suggestions: 1. It wasn't clear to me what you do right away. The book image is what helped me. Then I still wasn't sure if this was a digital book or not till I read the "How it Works". 2. I think having an example for a wedding book would be useful.

Good luck!!

Edit: Just found the examples :)
