Nice!

(Makes me wonder just how much such an animation would show if someone were
to take some of the shots of the Crab that go back a few decades, I know
that
it is expanding, but wouldn't it be wild to actually *see* it right in
front
of you?)

I remember seeing b&W photos with a positive with a much later negative
overlaid. Without expansion, the two would have covered each other. But they
didn't and the light areas showed the expansion.

Yes, I remember seeing that.
