This low-resolution and block-made pseudo font (and its dot-made clone "dot see") show an interesting distortions: an aliasing. With an extra gray value, we could take advantage of this 'feature' (which is not a flaw). For instance, one could easily clone "choochest" (if allowed one day) just to add this halftone (by using a second block element, with less surface). In this, your numerics lack this style (and feasibility of antialising, as is). I could not add "choochest" to my list of future archive, just because your matrix is a tad too large for a minimalist work. What was your inspiration for this fontstruction? (not the uppercase letters, I'm sure!)
