Hmm, that's new to me; I'll have to look it up. Sounds interesting.

I gave that some thought; but the video image background has such a limited
field of view that I thought it might look strange as a 'spherical' reflection
(i.e., mapped to a sphere.) The problem with using a sky_sphere is that my
police car renders need a transparent background (for compositing later); I
don't *think* a sky_sphere can be made no_image (?). But I could be wrong about
that.

The reflections do need better imagery, though. I also thought of going out in
my driveway and making some stitched-together photos of the surroundings, from
the 'location' of the police car. But my original background movie was made last
Spring, when all the trees etc. were in bloom; now it's winter and the trees are
bare! :-/
