Mayans also have languages that are heavy on iconicity. In any of the different Mayan tongues are huge numbers of verbs detailing the shape of objects, their patterns of movement, sounds, etc. Different consonants and vowels associate strongly with different aspects of these (much more than the weak associations one finds in European languages). I've worked with data from about 10 of these languages. You guys should get dictionaries and grammars to really get a feel for this sort of thing.
