Light clocks ideas using a world to a 12 hour clock face, basically divided by the north and south hemispheres. The original one has numbers around it, but going anti-clockwise, as the Earth goes around the sun. It has a 0-6 measurement.
However, then I thought that some light even gets to the poles in mid-winter, so I thought I’d use a 12 measurement system, with 3 the lowest rating.
I couldn’t see anything like it online, so is it original… and worth thinking about? Or has it been thought about, but not been considered worthy?
