ProtoSans22 by Roman Gornitsky is a free geometric techno display font built from stark right angles, squared curves, and broad, nearly uniform strokes. Its open shapes look deliberately schematic.
Its early digital character suits electronic music posters, game graphics, and technology branding, where the blocky construction echoes simple screen icons. On event merchandise, the letters can become part of a circuit-like border or modular emblem rather than serving only as ordinary text.
