Here’s an interesting literal take at converting an existing real-world book into an iPad book. The LoudCrow crew (makers of one of my all time favorites, The Night Before Christmas) have done a good job at making a sweet simple reading experience.
The story is simple, the illustrations are cute, and the interactions are fun. For example, the screen fogs up when you turn on the hot water in the bath tub (you have to wipe it off with a “squeek” “squeek” to read the rest of the story), fish that leap as you touch water, and stars that populate the night sky as your finger rolls across it. All around a solid read and a good story. Good job taking a pre-existing work and giving it new life.
