NEW : Precession Added

For flash users, we now show the precession of the Earth's axis. As time goes by the direction the poles point changes and we now show that on our display. It moves in a slow circle taking about 25,700 years to complete a revolution. The most noticeable effect is that the zodiac (which is linked to the Earth's tilt) moves around with time.
