If they didn’t use an entire browser to render the clock face this seems like it could be an Arduino/ESP32-esque project.

#24Earlier quoted context omitted.
There's a Kickstarter project to make a round phone.[1] That had potential as a female fashion accessory. But the site hasn't updated since 2025.[2] [1] https://www.kickstarter.com/projects/dtoor/the-cyrcle-phone-... [2] https://www.cyrclephone.com
What makes a fashion accessory ‘female?’

#25Are there epaper versions of those round displays? Maybe I'm old fashioned.

#28> I also tried with a Raspberry Pi Zero 2, but 512 MB of RAM were too little to run a modern browser, sadly. I found that the surf browser was efficient enough to run fine on my Raspberry Pi Zero W. YMMV with animations and such, but it's much better than any chromium alternative in my experience.

Re: How to build a circular LCD clock
#30I see some comments pointing out that the clock wouldn't need to run in the browser. I picked this option to make it simple for folks around me to quickly prototype their own clock faces. This isn't supposed to be the cheapest or most efficient implementation, either; feel free to build your own LCD clock and then blog about how you did it!
