K73r
Public Type · Lauren Graycar

A constructivist geometric sans built from square, circle and triangle, offering five styles and over 10,500 glyphs with up to 100 alternates per character.
About
Developed by Lauren Graycar over two and a half years, the typeface applies a strict geometric grammar — square, circle, triangle — to produce letterforms that are simultaneously systematic and inventive. Five styles (K89a I through IV and an italic K73i) expand the family's range, while 20 stylistic sets and extensive discretionary ligatures give designers granular control over the character system. The vast glyph set includes lining and old-style figures, diacritics, currency and mathematical symbols, covering a broad range of Latin-based languages.
Classification
Built entirely from three primitive shapes — square, circle and triangle — K73r is a rigidly constructivist geometric sans with an experimental, modular character system that places it firmly in the display category rather than functional text typography.
