Doku by Tamer Koseli is a free futuristic display font with broad monoline letters shaped by continuous rounded turns and sharp diagonal cuts. Its open forms and unusual joins give the alphabet the look of custom electronic signage rather than conventional techno lettering.
It can create a sleek interface title for science fiction entertainment. The smooth tubular construction also fits electronic music packaging, large event posters, and fashion branding with a deliberately experimental edge. In those settings, the letters can become part of the graphic itself, extending into circuit-like borders or angular emblems that echo their clipped corners and continuous linework.
