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.
