I assume you do not own a wall clock?

I make these https://www.stationdisplay.com/ . They are also just as "useless" as a wall clock yet people find it a lot more pleasing to take a glance at something to give the information instantly, than having to make multiple decisions in order to take their phone out, open the app and find the place with the information they need.

Yeah, I doing something like this for me. An ePaper display to show local departures of public transport and QR code for my local network.

Having the departure times of my local tram right next to my door helps to not miss it by half a minute. =)
