Never seen anything like this in Turkey. We have a simple red on white “E” (first letter of Eczane=Pharmacy) with maybe very timid color change animations, time and/or temperature switches.
As others have pointed out, these look like quite the distracting and cyberpunk dystopian ad signs, most unexpected for a core health institution.
Switched from the default win10 mail app to thunderbird about a year ago when the mail app started forcibly updating to the outlook and broke some shit on my windows installation to use a whole lot of resources. I quite liked the old mail app of the windows, but Thunderbird is quite enough of a replacement at default settings and much more customizable after fiddling. K9 has no difference than Gmail on default settings, either.
