Pimeroni has a selection of eink displays up to 7.3" including some with various buttons and LEDs to make whatever you'd like. https://shop.pimoroni.com/search?q=inky

All boox tablet/e-readers just run Android. They can do literally anything Android can for folks asking about the loading and displaying of the web page. There are several "kiosk" apps and browsers with kiosk modes. Also fairly expensive Android automation tools.

That's cool, but:

> It takes approximately 40 seconds to refresh this display

I think that would rule it out for the purpose of this project - the demo in their introduction video[0] shows that it flashes multiple colors for ages during this long refresh. I imagine that could be very confusing for someone whose short-term memory might not last that long.

The colour screen have a much slower refresh than the others. The greyscale one I have takes less than a second with minimal flashing.

Yeah, a black and white version would probably have been fine. Somewhat frustratingly they don't seem to have a 7 inch greyscale one though, only colour versions! Maybe they used to but stopped selling them?

EDIT: posted this before I noticed harpastrum's comment
