In a novel use of mixed electronic and traditional media, Japan's Mobile Art Lab created "PhoneBook," a children's picture book that becomes interactive when you slide your iPhone into it.
Using the phone's touchscreen and a switch that changes the scene when the page is turned, the book - currently just an art concept with no indication of when it may be commercially available - opens up new possibilities for interactive media. The art group's intent was "to create a new parent-child communication through the mobile (phone), and their website (auto-translation here) says that they want to extend the concept into "magazines and books," which could lead to more such experiments and -one hopes - possibly a product that you could bring home to your kid one day.
This thing would be an incredibly popular Christmas present if it were on the market.
