You got me curious, so I gave it a try with the graphic in the article!

There's two toruses in the clip, one with the daylight on the inside, one with the daylight on the outside.

One thought I had while making this is that you could visualize multiple years, or even someone's whole life, as a string winding a long spiraling path down the length of a helix.

Very cool. What program is that?

It'd also be nice if the colour was not just day/night, but the actual predicted daylight at the time of day, which would result in a continuously changing colour.

I guess at that point, the sine approximation from OP would no longer apply, and https://en.m.wikipedia.org/wiki/Sunrise_equation would have to be used.

It's Blender! Great OSS project.
