So, I’m still updating and expanding on Omyatloko. I’ve begun to catalog various sets of possible glyphs first by shape and then by position. This seems to be the most efficient way to keep track of the glyphs, and I have tried many ways.
As you can see, it’s the “hand” radical rotated and combined with the vowel markers (which do not actually covey any phonemic information unless said “hand” permutation is assigned a consonant sound).
Some of the sheets are – so far – full of unused glyphs, while others are filled with many already assigned glyphs. All in all, it’s progressing, but there is much left to do.
