simple warp of a 2D movie

I have a feeling a big “duh” head smack is in my near future, but I’m not having much luck at the moment. I want to be able to warp a movie image in the center to give the feeling that you are passing thru an imaginary boundary in some way. As my partner said, “something like this?”:

*sigh* … yes, something like that. Movie mapped to a big rubber sheet that I can lightly push and pull from the center to warp…just a little bit.

Any pointers on objects I should look at. All my processing is already in gl-land, so maybe a simple way to deform a video plane or ??
