I have something similar that shows when the next bus is leaving our nearest stop.

I really like it, and I would be tempted to invest in something larger for putting my calendar on the wall in my home office, but the big problem with this sort of thing is that cases are always a disaster.

My bus Pi is in a really janky case because there was only really a couple that would fit with the ePaper display on it.

If I could buy something about A4 size, in a sleek case that I could wall mount nicely, and have good hackability on, I would absolutely do it.
