MoMA Exclusive: Designed by Danish architects Allen Shakir and Ewa Bryzek, the Delta Wall Clock is made in Poland. Taking inspiration from sundials, which tell the time with shadows, the Delta Clock’s face has “folded” surfaces that create interesting shadowplays when exposed to sunlight. The shape and folds of the clock are created with CNC technology, a precise process involving computer-numerical control of a wood cutter. The Delta Clock tells time silently and measures 3h x 12"diam. Requires one AA battery (not included). Easily mounts to your wall.
