I was wondering about emoji's too. That could work rather well. I think if you had a 2d array of like 200 unique emojis, with some subsection-ing of like, quartile, you could simply say, "If your train has a crocodile in the top left square, a star eyed in bottom right..."
There's some paper discussing how high dimensional parameters can be visualized with human faces, because aspects of the face are quickly identified by humans. I think they used ideas such as, How far the eyebrows are apart etc. Maybe making (disfigured) human faces with binary features would be easier to parse too.
In any case, what I've come up with is well below optimal. I'm not sure I even need the number of bits I've included, but I show them as some kind of worst case.
