GridDadaA by Manfred Klein is a free geometric dingbat font built from sparse grids, ruled lines, circles, and sharp perspective angles. Fine strokes and solid round marks give the symbols the look of modernist diagrams or architectural sketches.
Posters can use these linear forms as structural artwork rather than conventional lettering. They also fit experimental publishing, exhibition graphics, and music packaging, recalling plans and technical systems. Each symbol can become an illustrated panel or map-like interface element.
