Threethree GeoSemiRound by david t of FontStruct is a free futuristic geometric sans serif with a slim monoline build. Its tall letters combine squared curves with clipped corners and small angled cuts at key joins. The result is crisp and distinctly electronic.
Digital graphics are its most natural setting, especially game interfaces and technology event posters that benefit from lettering resembling a custom display readout. Electronics packaging can use the same precise shapes to suggest engineered controls rather than generic science fiction decoration. For device branding, the repeated notches can become a recognizable product motif.
