This started out as a joke, but it just kept getting more interesting to me as it was developed.
Completed countertops can contain at least two pieces: an uppercase and lowercase letter. The left side of the counter starts with a capital letter, which has a corresponding right side piece in the same lower case letter. Numbers and Shifted Numbers contain center pieces that can be typed in multiples.
The <>, [], and {} make special faux perspective counter pairs. Use sparingly.
Another example of glyphs acting as the counter in a space, and this space filling the usual "glyph's white space" in the way the counters were described for the competition.
This font was inspired by crockery decorated with a name which I saw offered in a car boot sale. My font's UC has delicately decorated glyps, visible before food is placed on the plates; LC shows plates after the meal, with food remnants covering/filling parts of glyphs ;)
Inspired by the Maze Set. A technical fontstruction showing the usage for thinner macaroni bricks. The logic for possible counter relation:
1) Every letter is filled with thinner version of itself (self-pattern fill).
2) Outline vs Inline, emphasizing the "opposite" meaning of counter.
