It would be cool to see such a video properly done, based on actual science. Alas, I haven’t any skill whatsoever in this area.

I saw one web page that tried to explain the earth’s orbit, and precession of the equinoxes, with respect to the plane of the galaxy, using animations. Unfortunately the point of view of the animations was itself orbiting the sun (or, alternately, the diagram was rotating while you watched it), and that was never stated, so one would see added rotations in the graphic that made no damned sense. (Hint, don’t try to talk about rotations in a frame of reference that is itself rotating, if you want to be clear!) It took me five or six views of it to realize that the producer of the video was either trying to obfuscate things, or just made some profoundly stupid choices.
