Just like in David's FE Clock app, the hand indicates the sun's path across the flat earth.
But when your city is placed at the top, like Montreal here, then
the hand follows the sun's path in your city's sky.
The two pie slices on either side indicate sunrises and sunsets from one solstice to the next.
This clock also becomes a compass.

This is where it's getting interesting because everybody,
not only flat earthers, might be interested in this clock.
And once they see how this clock matches reality,
they become more open and curious to investigate FE!

Measuring time in this way takes us off the beaten, robotized track,
and brings us closer to the natural cycles of life.
