I await the day where a mathematical paper is extensively using emoji.

@tpfto well, I just had one at work that was using runes. So maybe hieroglyphs and cuneiform are equally likely?

@pkra yes, perhaps...

@tpfto not quite math but Hefford/Wilson/Wang, "Categories of Semantic Concepts"

@elilla an interesting example, nevertheless. @christianp, have you already seen this?
