Designed for the Museum of Modern Art, this perpetual calendar captures the essence of pure, minimalist function. The calendar can be placed on a desktop or mounted on a wall. Its string-tethered gravity-defying ball is suspended in mid-air, and moves manually to mark each month, while a second magnetic ball securely perches on the horizontal beam to indicate the day. Approximate size is 13 x 9H inches. Size/Dimensions: Not Available Type: Home Accents Color/Finish: Black
