How about putting the video as an image on a light, and constraining the light to point out of the camera, like a projector?
that would be most like the demo concept.
I thought I needed front projection mapping like solution 1 on this page
but now I'm not so sure, because I don't know if front projection maps will render in any view or camera other than the camera that created them. I was going to test it, but I can't find the feature in v13.
I like the idea of actually creating a projector. I like Ben's idea of moving the spheres, too; although that would mean writing a little program to mirror the camera's movement.
