oh dang - looks like I missed the boat. They have an example with a bone structure to warp a bit file - exactly the kind of thing I could use as an example, but the example file link is no longer working

Sorry, I am a complete noobie! I can't think of a proper way to animate paper curling. The effect I am trying to accomplish would be like grabbing a flat sheet of paper from only a single corner and pulling it across the face of the paper. Or possibly like a sheet of paper blowing around in the wind...
