MPFoldTransition - Easily add custom folding and page-flipping transitions to UIViews and UIViewControllers

MPFoldTransition is a set of classes to add folding-style transitions to iOS 5 projects.

This is a really amazing project. Making these fold and flip transitions is a ton of work and Mark Pospesel has made it dead simple.

You can easily transition views using different styles with one method call:

+ (void)transitionFromView:(UIView *)fromView toView:(UIView *)toView duration:(NSTimeInterval)duration style:(MPFoldStyle)style transitionAction:(MPTransitionAction)action completion:(void (^)(BOOL finished))completion;

There are versions for UIViewControllers as well.
