Designed by Gideon Dagan for the Museum of Modern Art, this perpetual calendar captures the essence of pure, minimalist function. For display on a desk top or mounted on a wall, its string-tethered seemingly gravity-defying ball is suspended in mid-air manually moves to mark each month, while a second magnetic ball securely perches on the horizontal beam to indicate the day. Constructed of injected-molded ABS polymer and magnets.

The ball is stopped by magnetic force.


Create different geometric patterns, depending on the straight and curved.

It is also ideal for gifts in a nice box.
