chirp
An interface to convert strings to sounds (twitter -> chirp, chirp).
I figure if they are discernible patterns, they could make a good accessibility tool. Many already use incredibly quick enunciations as their default screen reader settings. Morse is another option.
But if it sounds like actual birds, you could have your mobile chirp you updates, entirely doing away with looking at the screen while potentially providing you with a private language.
Expected release date: September 2020.
