Multi-touch Crop

I have recently changed the final student project in my OOP class to a multi-touch app. One of the briefs I gave to students was to do a non-destructive crop on the multi-touch. Two students, Jae-Ho Yoo and Morgan Roddick made a short video of it in action and I thought I would share. Check it out and give them some feedback, I am sure they would appreciate it.
