ProtoSans41 by Roman Gornitsky is a free blocky techno display font built from strict right angles and broad, uniform strokes. Its squared forms have blunt joins, flat edges, and compact rectangular openings. The lettering resembles modular signage or an early low-resolution screen, but its oversized shapes feel more architectural than pixelated.
Digital graphics are a strong setting for this construction, especially game interfaces and electronic music artwork. It also suits posters and event branding tied to technology, club culture, or experimental design. The likely audience is designers working in technology, youth entertainment, or music who want an austere, machine-made voice with the impact of custom lettering.
