While the app-smashing term seems well known and understood by teachers and students exploring creative uses of iPads in the classroom, I think I may have stumbled upon another idea, App-Hacking. I am no hacker and will readily admit that the term may be a bit misleading, no worries.
App-Hacking: Finding uses for apps or combinations of apps to use them in ways that they were not originally intended.
My first app-hack: Layered Green Screen Writing

I don't intend for this to be a daily process or even to be considered a terribly thoughtful idea for iPad use. I can see students that are experienced with video creation on an iPad to add this sort of customized layer to their videos. Ultimately, I think these sorts of experiments are more about thinking creatively and pushing the limits of what is possible with any particular tool. Consider it a sort of experiment in creativity.
