I’ve seen these all over Europe. Some have simple images of the cross flashing, some have windows screensaver esque animations, and some have 3d renders of various things rotating in all sorts of ways. Why is that? Wouldn’t a simple green cross be enough to get the point across, or do they need to be overly verbose? Here’s the full video instead of a gif
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.
