lately there's been a lot of people in my community trying to revitalize the old writing systems that were used for nahua and maya writing. i'm far from fluent in nahutal to begin with, but its exciting to see. neither is likely to be available digitally for a long time, so i've been experimenting with using cree writing to make it a little easier for me to remember how to spell stuff. i think the old ways of writing are really beautiful and i'm happy to be a small part of bringing them back. one of the fun things about maya writing is that its really hard to describe the logo-syllabic structure in unicode so they've been creating this whole rendering engine to handle complex stuff like maya writing and egyptian hieroglyphics. probably another 10 years before it supports these systems.
this video gives a basic introduction to maya writing which has received a lot of attention. afaik nahua writing has only been regarded as "real writing" somewhat recently when the academics started to understand how it work.
alphabet writing is boring and easy to encode. give me something interesting that computers can't really grapple with. now that's advanced writing!
