I hacked the wonderful children's book "Brown Bear, Brown Bear". I used conductive tape and wires from old telephone wire. I found the audio clips online and imported them into Scratch where I assigned the sounds to the number keys by using the "remap Makey Makey" function. I originally envisioned using the book to share facts about how environment change (global warming) impacts various animal species. This project could also be used to create a multimedia book that reads to you and has sound effects. See the Scratch program I created here: https://scratch.mit.edu/projects/351428088
