This is a fancy HTML5 clock that I made from a mental image that came to me in a flash.

The "Stackoverflow" algorithm for calculating the position of the sun comes from this stackoverflow page and answer. The algorithm was created by R. Walraven (Solar Energy. 20:393-397). Then, it was refined by J.J. Michalsky (Solar Energy. 40:227-235). It was converted into code by David (lindelof) in the first answer on this stackoverflow page (originally this link, but it is now a 404). Then, some angle errors were corrected by Josh O'Brien in the first linked stackoverflow page and answer. Finally, the code was ported to JavaScript by me for use in this website.
