Can I watch an Eclipse with The Fourth Day?
How does The Fourth Day display Equinoxes and Solstices?
Do I need a 3D graphics card?
I have a 3D graphics card, but it doesn't work...

Yes, but... The
projection of the Sun and Moon on the Earth as shown by The Fourth Day, are
not the actual size (they would be too small otherwise). As a result, these
oversized Sun and Moon images may overlap at times when there is not actually
an eclipse occurring. These locations also display where these bodies are
directly overhead. Solar eclipses in particular are not even visible from all
places on the earth, and the alignment will depend on your viewing location on
earth. A more complete Eclipse simulation is planned for future versions
of this program. 
On the Winter and
Summer Solstice, the Sun reaches the Tropics of Capricorn and Cancer and
during the Spring/Autumnal Equinoxes, it passes South/North of the equator. To
see this happening on the globe, you will need to turn on the
latitude/longitude lines. The equator is represented as a red line of
latitude, and the tropics as blue lines at +/- 23.5 degrees.
