Can't really contribute as in Germany most pharmacy signs are pretty static and look kind of like this: https://cdn.pixabay.com/photo/2014/06/30/20/59/pharmacy-380780_640.jpg
But I also wonder why there's so many pharmacies in France. In almost any city I've been to it's hard to not have a green flashing cross in sight.
Many communities exist, but mostly on paper.
What I haven't found yet is something substantial and informative like /r/askhistorians.
