Lovely topic and amazing images, thanks for sharing!
(Sorry the forum defaults are a bit strict, you should be able to post multiple images now)
Reading your bio @gundega.strautmane, it’s super interesting that you have worked with Braille, which I guess is also an invented alphabet. This reminds me of Hangul, the beautiful alphabet used in Korea that was invented in the 15th century. I understand is easy to learn, partly because some of the shapes are based on positions of tongue and teeth needed to make the sound.
@lukexi and I are exploring making alphabets together as well, early days and I’m tied up this week but will find some time to share some thoughts soon!
