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.
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.
