I have been a huge fan of parametric design and designs based on modules. During my years at the London College of Communication, I designed this typeface using Glyphs.
Modulo is a layered geometric typeface designed on a 128 units square grid. All 21 weights and 8 styles are defined algorithmically according to simple rules. Because all letterforms are contained in a square, they all share the same metrics for easy layering.
