In a bout of insomnia, I came across this article on FastCo about a new app for kids, The Human Body. The design of the app immediately reminded me of my childhood pop-up books and The Magic School Bus, but I loved the talking points on how the app is built.
The development team worked with an children's book illustrator to bring the offline medium of a children's book to life in an iOS app. I love their approach to bringing together an interdisciplinary team of artists and developers, and the mediums of online and offline together in a beautiful and educational experience. http://www.fastcodesign.com/1673309/as-beautiful-as-a-golden-age-picture-book-an-anatomy-app-for-kids#4
