I looked at your website advertising the celestial sphere convenience
for observing and that is fine if  you consider astronomy to be  just
an exercise in magnification.

"Planet Vista displays the solar system on your desktop background in
real time.  Watch shadows transit Jupiter, see today's sunspots, or
follow a Lunar eclipse. " Skywise

When you look at the shadows cast by Jupiter's satellites they contain
a lot more information than the usual 'transits'.Depending on where the
Earth is in its orbit,its orientation to Jupiter  determines the
position of the shadows  giving a much clear picture of our motion
around the Sun along with Jupiter .

The motions of the Earth and Jupiter around the central star (which
creates the shadow in the first place) is a wonderful way to appreciate
our orbital motion but like the rare  event of Mercury overtaking the
slower moving Earth with the central Sun  as a backdrop,it goes
unappreciated in a world which thinks astronomy is all magnification
