Another modular concept!
My idea was to create letters that could be rotated 90° to create other letters, for example C > U > N > D and B > M > E > W.
Meantime, in making my Japanese/Chinese comic lettering font for Comicraft, I learned that Kanji are constructed by combining several words into a single character.
For example, the box shape below top left is “mouth”, and top right, mouth+dog = “bark”.
I see some interesting possibilities happening, but it will probably take a lot more trial and error to become something that really works and is readable.
The uppercase has the interlocking pairs but lowercase doesn’t, so you can take your pick. And I included the initial Heavy weight too, because it wasn’t bad.
Enjoy, and let me know what you think…
