Just a doodle. Reminds me of typesetter's forms.
Every pixel of the negative space is trying to approach the letters in the positive space. But, they are repelled from the letters by a 1px border. This leads to a look that is not quite filled, not quite grunge, and not quite maze-like. The filled voids seem obviously anomalous, but can only reinforce the forms they attempt to engulf.
"Tacit Affront" is an anagram for "Artifact Font".
