The iPad was meant to be turned into an Etch-A-Sketch! With the officially licensed Etch-A-Sketch case, from Headcase, combined with the iOS app, you can wow your friends, classmates, and colleagues. Everyone has thought of it, but Headcase went ahead and did it, for both the iPhone and iPad.
You can't help but smile when you see the case. And when you use the app, it all comes back to you. Of course you can shake it to erase it... It wouldn't be legitimate without that feature!
