The books are super easy to create, can include a mix of pictures and text. Pictures can be imported from your computer so you can use your own pictures or download pictures from the internet. When you create a book the owner can specify the privacy settings. See the Zooburst gallery for some interesting examples.
I have already had teachers try this format for Science presentations on how the sun creates energy, I could also see using it to:
1) Tell a fractured fairy tale in Language Arts
2) Detail the life of a famous figure from History
3) Give a tour of a cultural region in a World Language class
4) Have English Language Learners tell a story using new vocabulary words.
