Furniture Design Mob-Clock Clock by Nazanin Saranjampour Mob is a desk clock formed by a graded Mobius strip mounted on a stand, with a small ball serving as the pointer. Time is a linear concept, yet common clocks repeat two cycles each day, AM and PM. On Mob, the ball moves in one direction along the single boundary of the Mobius strip and passes 24 hours without repetition. The main body is injection molded from PC and ABS, and the legs are made of metal bars. The clock marks time in steps of 15 minutes, without seconds, to support a calm and natural sense of time.
