From Wikipedia
"In astronomy, an analemma is a diagram showing the deviation of the Sun from its mean motion in the sky, as viewed from a fixed location on Earth. Due to the Earth's axial tilt and orbital eccentricity, the Sun will not be in the same position in the sky at the same time every day. The north-south component of the analemma is the Sun's declination, and the east-west component is the equation of time. This diagram has the form of a slender figure eight and can often be found on globes of the Earth."
I love the way the pattern is there above us, hidden only by time.
