too much trouble to ask one responsible person familiar with graphics

to set this image in motion in order to project a more accurate and

more enjoyable explanation for the Equinox -

There you go again, using that graphic that demonstrates PRECESSION, and has nothing whatsoever to do with the Equinox... nothing at all! Note that there are stars in the background... STARS! The graphic shows the Earth's axis moving WRT the stars, which is certainly does, over the course of 26,000 years. Over the course of a single year that axis moves NOT AT ALL, it points at Polaris constantly. You are using a graphic that is completely inappropriate for the point you are trying (and failing miserably) to demonstrate..

Here is your graphic again, this time with an actual explanation of what it represents...
