The Wonderbook is a collection of graphic AR codes spread across a series of pages; no text in this book. Placed in front of your TV, it works along with the PlayStation Eye and PlayStation Move.
Much like Sony's EyePet, actions are mirrored on the screen. The book gains beautiful illustrations and text, and animated objects pop out.
The "book" itself is a series of boards with AR codes. The Wonderbook will be a universal peripheral, working with all future titles (not just "Book of Spells").
Here's the cover of the Wonderbook, which Sony says is also waterproof. It's durably built.

Some parts of "Book of Spells," the J.K. Rowling Wonderbook Sony demonstrated, turn into more-traditional mini-games controlled by the Move.
