To blow my own trumpet a bit: https://sunclock.net/ https://sunclock.net/ If you turn off the numbers you get a pretty decent and (i think anyway) culturally assumption-free clock. It tracks the sun and moon, shows the seasons (in #calendar). The direction it turns matches the way the Sun moves in your hemisphere. More generally, I think 24-hour analogue clocks are already pretty culturally neutral — I don't understand why we ended up with 12-hour clocks being the dominant form.
