I was looking for a font like http://www.dafont.com/calculator.font , but:
A. Thinner
B. Each line in terms of length is proportional. (space vertically is fine)
C. Instead of the slanted edges, completely straight ones.
I'll make a mockup in the morning of a letter with the features I want. If a font like this doesn't exist, I've toyed around with FontForge and it seems like I could create my own like this.
Thank you in advance.
