Interactive Children's books

As mentioned in the post below I want to include interactive elements into my book to keep the child interested and excited to learn. I have picked a selection of books I think are appropriate and interesting to play with. It also gives me an indication in to how the mechanics of these elements work.

The Jolly Postman is a classic and offers unique interactive elements with its envelopes and letters. This Christmas version also include even more activity aspects such as jigsaw puzzles and games.

This book is full of flip ups and pull out. But
I a specifically interested in the pull out elements
as this is something i have in mind for my own
designs, i think its a great way of drawing
the audience in. I'm thinking of a hide and seek
approach, similar to the concept of this book.
This is a great example to prove this theory works.

This book shows some really detailed and complex
pop-up's. They look  great with it's minimal text,
it's a very visually focused book, which is constructed
in a brilliant way. I love the use of descriptive words
that sets the scene perfectly in your mind. Although
this is a very visually stimulating book, it's
quite predictable. I want to include rhythm and
routine but i also want to include an element of
surprise and suspense.
