RANDO SANS — A HANDWRITTEN FONT THAT CYCLES VARIATIONS AS YOU TYPE

Summary from the TLDR Design newsletter

Designer Beau Maher created “Rando Sans”, a free handwritten-style font that cycles through multiple versions of each character to create a pseudorandom effect using OpenType's Contextual Alternatives (CALT), after discovering the built-in RAND function was limited and poorly supported. By building complex class-based substitution logic (and using ChatGPT to automate repetitive code), he solved duplication and sequencing issues to make the font feel more naturally varied—showing how designers can experiment with technical systems to solve creative problems.
