ProtoSans03 by Roman Gornitsky is a free geometric techno display font built from squared, near-monoline strokes. Its open joins and sharply cut corners give the letters a modular, engineered look. The forms are spare and angular.
Digital graphics make a natural home for its screen-like construction, especially in game interfaces and electronic music artwork. The same precise geometry can shape packaging for hardware or experimental products. It also suits event posters with futuristic or architectural themes.
