Barefoot Books World Atlas ($8) is a kind of digital globe for children, giving them easy access to a simplified cartoon overview of the whole world.
From the orbital view (for want of a better word), you see the globe peppered with hundreds of colorful icons. Spin the globe and zoom in. The little icons grow and become tappable controls. Each one reveals a snippet of information in text and audio form (read aloud by the UK’s favorite TV geographer (yes, we have those), Nick Crane). There’s also a photo to look at for each fact, which is often much more informative than the icon was to start with.
