I've been really digging into super minimal 3-block typefaces for the purpose of weaving with a taquette block structure. The strict rule was 3px high for letters, with variable with as needed. Less than 3px height was acceptable for punctuation. My focus was on legibility of the set, clear character identity (no duplicates), and differentiation of weight between upper and lower case, when possible. I think works OK, given the constrains. I'd love to hear your feedback! What is your take on that lowercase g? I'm always tweaking it bit by bit. 

Cheers, 

Jeff
