Inspired be the "a" in "MOS 2018" by Pabloariel2004, and how it seems to be made of itself in Morse Code: ".-" .
Only one other font seems to have its letters formed by their corresponding Morse Code, which is "Learn morse code" by Christian Munk (CMunk).
Letters like E,I,N and W are visibly affected by the constraint, but still look sorta cool I guess
EDIT August 30, 2018: The I looks better now.
A script used by the Old Fyromrese or Lesser Oinai (human-like) people of Planet Fyromr in my own stories and games. The runes depict looms, which were made by splitting two sticks, one to make the internal frame and one to make the hexagon shape. These runes were typically carved into wood.
The earliest Fyromrese writing was done using cord wrapped around pegs on these looms, and so this script attempts to mimic the path of the cord. The later Fyromrese (Tangled Script) took things further, making it possible to encode entire words within a single loom-shape while also making individual words and letters far more readable. But that script requires multiple colors to render legibly so it probably won't be possible to Fontstruct it.
Notating Fyromrese numbers using a Fontstructed font is similarly unlikely, as the logic of their enumeration would require hundreds of glyphs.
This script attempts to match loom-shapes to phonemes as they are spoken in American English.
