I've been staying at that click for a solid ten minutes, but I can't figure out why minutes and seconds start on top, but hours on the bottom. Any idea why that particular choice was made?
From the sibling comment's link: "Noon is at the top, so that the hour hand mimics the path of the sun."
Adding additional info to my sibling comments. Since the bottom is designed to show night, it would be cool to grab a geolocation and draw the bottom based on sunrise/sunset times.
the 24 hour clocks I've seen usually are set up like this so daytime is the top half and night time the bottom - as though the tip of the hour hand was the sun
