That modak font looks similar to one in Pixel phones clock.
But Nice thing you made there :)
How to build a circular LCD clock

Re: How to build a circular LCD clock
#12How to build a circular LCD clock, step 1: buy a circular LCD that looks like a clock. I'm not kidding, that's the extent of the build. They simply connect that display to a computer over HDMI. The only hacking here is browser-based JS for clock animations.
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]

#13you can also do this with an esp32 as long as you don't insist using a browser to draw a clock
That's what i wanted to say also. The raspberry is a total overkill here.
Nice implementation though!

Yeah, LVGL is probably what you'd want in that environment.

You don't need a browser to display graphics. And you don't need to be a programming whiz either. I'm sure Claude could write some python to render these clock faces.

I know this isn't exactly a serious product and more of a gadget/gimmick but man we are off by a factor of like 3-4 here :D

What makes a fashion accessory ‘female?’

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