There's something called a "Wandering Hour Clock" that, well, displays the current time in an interesting way. When I ran across a 3d printable version online, I knew I had to build one. A picture (or two) is worth a thousand words: https://www.printables.com/model/327198-improved-wandering-h...
Of course once you have an ESP32, you might as well put the clock on the network and get time over NTP. So the above project includes that.
I added some features, such as fractional time zones, and being able to set the time zone and DST from the web interface rather than in code. My software changes have been upstreamed, so the above project now has them. I also added a few small 3d printable covers to make the back of the clock look a little cleaner: https://www.printables.com/model/688154-mounting-plate-and-e...
Someone upgraded that project to use a stepper motor controlled with an ESP32: https://www.printables.com/model/688154-mounting-plate-and-e...
