To get back on subject here, I just learned a little about the Analemma Curve this morning. To wit:

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 the 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.

And guess what? If you plot the sun's appearance in the sky over a full year, the deviation looks like this:

Well, well, well: doesn't the curve plotted over a year look a little like an infinity symbol?

The image above is from www.analemma.com's site.
