I think the novelty comes in exactly what you state, and I think that the educational system relies too heavily on the status quo. There would be nothing wrong with a classroom posting pictures of Harry Potter and couching a lesson in the Harry Potter clothes in order to drive more student involvement. It's no different than when Jeopardy was popular 10 years ago and Jeopardy-like student challenges spread across schools.
With respect to the copyright infringement aspect, I hope that is not the case. I believe that many people are visual learners and seeing an example can have a much more powerful result than a mere description. It was with that intention that I posted the video. I do not plan to distribute the app as that would clearly be in copyright violation.
