Now this is a fantastic idea. The Japanese firm Mobile Art Lab has turned the iPhone into an interactive children's book with what they're calling the PhoneBook.

This is not the first iPhone-related program aimed at your toddler – you could spend hours looking through all the child-related applications available on iTunes – but this approach, with its book-like accessory framing the touchscreen, is an idea that is bound to catch on. Mobile Art Lab has stated that these kind of applications are not limited to children's books, but could also be utilized in other types of media such as catalogs and brochures. Graphic novels and manga could easily integrate this technology as well, but the interactive potential makes this an ideal learning tool.
