Codes go back as long as has been human communication…. and miscommunication. Binary informs many of the pattern codes– a logical, sequential pattern of Yes/No-Dot/Dash. But then there are hieroglyphs and Hobo Code (yes, that is an actual thing) which are all iconic and representative… even metaphorical, and up for interpretation.
