ProtoSans34 by Roman Gornitsky is a free geometric techno display font built from stark, squared forms. Broad strokes meet at hard right angles, and tight junctions give the letters an engineered, modular look. Large rectangular spaces keep the dense shapes from feeling solid or blunt.
Game interfaces are its strongest setting, especially futuristic menus and titles with the logic of a machine panel. The same rigid geometry suits electronic music posters, technology branding, and science-fiction packaging. Its boxlike letters can echo circuit diagrams, grid patterns, and schematic illustrations, making the type part of the technical imagery.
