This font is a facsimile of a substitution cipher from The Shadow #10, "Chain of Death." Letters are replaced by blocky symbols, which consist of pairs of rectangular shapes separated by a space. To encrypt a message, the symbols are connected together by their outer right and left edges. This gives the appearance of a much greater set of symbols than there actually are, and the spaces will confuse potential codebreakers. There are no numerals or punctuation. I included square brackets ("[" and "]") for two special symbols that are frequently used to begin and end sencryptions (you can type messages [like this]).
Made on a whim as a result of rediscovering an old design (see sample).
It's pixel perfect at 12pt, 24pt, 36pt, etc. :^)
Since the inspiration image had only uppercase in it, I took some style liberties with the lowercase. The result is mildly comical!
One of those strange designs that sit in my note pad for ages and suddenly decides to become useful :)
