Although I’m showing how to use this game as a shift indicator, using black and white, literally as just visuals. They could also represent dots and dashes, which can thus be translated to Morse Code, it is often used by TV and News Papers within the background. I’m sure it won’t be long before you see what I mean, if you go looking.
Nobody thinks about the old ways of communicating, OK, with the exception of a few.

Just to add. About a year ago, I heard some crazy stuff coming over the CB frequency. I’m nosey and now and again I’ll scan all frequencies. It’s a video in the making.
