ProtoSans24 by Roman Gornitsky is a free geometric techno display font built from rigid, near-monoline strokes and square internal spaces. Open joins keep the forms visibly modular.
It can turn a title into a stripped-back interface element, making it especially convincing for game graphics and electronic music posters. The same squared construction gives technology branding and device packaging a purposeful, schematic edge. Science-fiction and retro-computing themes are its clearest territory, since the broken connections strongly recall segmented digital lettering.
