studied Blissymbolics many years ago. Found an old book from the
  1950s in a used bookstore. It was a well-spent $1.00. Icon-based
  universal languages can be tricky if they're forced, but as
  emoji communication continues as a natural extension of our
  native languages, it could easily replace writing. I've had
  whole conversations in emoji. You just "know" you've
  communicated successfully - it's a neat
  feeling.[1]blissymbolics_basic
