Cheap e-ink screen from aliexpress, running esphome pulling data from home assistant every 30 seconds. It got time and date, temperatures, time untill the next buss leaves from the nearest bus stops, range on my car, power usage and price, and the three next items from me and my wifes shared google calendar. I got it framed professionally by a local framing workshop. They were a bit confused and hadn't done anything similar before, but they did a great job. My wife isn't always a big fan of my home automation adventures, but she loves this screen!

I did something similar with a color screen+pi-pico for a rotating set of photos. It doesn't look great for everything though as the photos themselves need to play nicely with the 8-color palette of the service, and be reduced to a bitmap that can be read in.
Low-power consumption is cool though
