Some kind of great big ol' chain.
In retrospect, I think it looks like a jewelry chain from a dwarven civilization. Perhaps the hypothetical jeweler cut and ground the stones in an imitation of some dwarven font!
When glyphs are used in isolation, they somewhat resemble carved signets or seals. Increasing the letter spacing allows you to create a variation of the design. (This is something that must be done in-software since the font will render as monospaced by default.)

12SEP2018: Added lowercase... the low resolution combined with the design method make it very difficult to render distinctive lowercase versions of every letter, but I'll keep working on it. There's a lot of similarity between pairs like S/5, Z/2, etc., so this font is most effectively used in forms of writing wherein context suffices to inform the reader as to the identity of each glyph (lists, prose, and technical writings). If you want to use this in a password system or something, I recommend using one case's glyphs only.

Design Rules:
1. Negative spaces will be areas of 0.5 bricks' effective length or width.
2. Negative spaces may exceed the 0.5 measurement only by increments of 0.5 and in only one dimension at a time.
3. Glyphs will fill their framed canvasses to the greatest extent possible while adhering to the other rules.
When my mother was young (and specially after my birth) she supplemented the family's income from home by typing for students and businesses. When I was a student I used the same machine for my assignments, lesson plans and thesis. The years were not kind to the machine, the mechanics rusted or broke, the letters worn with frayed edges or disintegrating serifs and fine lines. Ruth's typewriter is a declaration of my appreciation of many years of service the brave little machine gave... As you can see I clearly didn't get the letters repaired ;) The font looks like I rearranged and glued down what was left of the raised surfaces, to continue using the typewriter and give my words a very modern look ;)) A "grunge-writer" ?? Did you notice that no typewriters were ever sold with this kind of modern destructured typefaces?! ;)
Since I started this font many years ago (Ruth was very amused and appreciated this hommage) this work has now become a memorial to her
