I saw esp32 picture frames That fetch images via WiFi, but this would be a lot of DIY.

My personal favorite is using all already always on devices such as a wall mounted tablet and let them have a screensaver that rotates through is set of images that change regularly.

It’s from a time where we didn’t have digital contact lists and no internet. So what if you want to call the bakery down the street? You look up a public record like YellowPages. And the same was true for people too. I know it’s hard to imagine now with plenty of Indian call centers social engineering grandma, but the only real “wow”here is why they didn’t change this yet.
