@samrye_enspiral . It is a good question. Who is it for?
I was thinking about a new way we can be introduced to the deaf alphabet. It has the American sign language (only the letters). I know that in sign language there are complex movements that mean a whole word, a full meaning, but this gives you the symbol for each letter for now... I believe is a small step towards learning a new language in the end.
