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.

I created this font with the idea that it would be written out and printed/screenshot/whatever and rotated right 90 degrees to be viewed and presented as it is in the game. I also added a visual difference between upper and lower case, as well as a few punctuation marks and symbols.

Here's the method:
Capitals and punctuation have rounded corners
Lower case has beveled corners
Symbols (numbers and such like $ # etc) have sharp/square corneres
