Dozen Dotted Letters by Arthur Druziani of FontStruct is a free outlined techno font built from rounded square nodes and narrow connecting strokes. Its letters resemble simple circuit diagrams or plotted paths, with open interiors and a deliberately modular construction.
The electronic reference makes it apt for retro game graphics, software branding, and science event posters. It can become part of an interface. In magazine features or educational publishing, the node-and-line pattern can echo diagrams, schematics, and maps rather than behaving as neutral lettering.
