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.
