First of all, thanks to clipka for the tips on how to do an overlay of image to
scene.

Secondly, I was trying to duplicate Rune's classic animation where he overlays
povray 3D on top of RL video.  I took some video with intentional hand-shaking
of an index card.  Then I was trying to figure out the math to interpose a think
box of similar dimensions onto the scene.  A real challenge!  Then I searched
some more and found out that when people have solved this problem, they write a
paper and set up web sites where one can "demo" the software that does it.
