Default More Equinox information

There are many articles out there presently with the usual awkward
explanation for the Equinox including hideous graphics -

http://earthsky.org/

With hundreds of billions of dollar worth of graphical resources
across many thousands of research institutions including NASA,is it
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 -

http://en.wikipedia.org/wiki/File:Earth_precession.svg

Watching the polar coordinates act like a beacon for the orbital
behavior of the Earth over the course of an annual orbit as they turn
wrt the central Sun is more in tune with the 21st century than having
the Sun cross the celestial sphere equator and sometimes it is
dismaying to see many good 3D graphics of Earth and no proper
perspective which shows the polar coordinates turning to the central
Sun rather than the older explanations which rely on variable 'tilt'.

The orbital motion of the Earth carries the polar coordinates around
in a circle and indicative of all other locations on the planet,it
should not be anything other than a pleasant experience to put this
perspective before readers with all the information and analogies at
our disposal.
