German designer Siren Elise Wilhelmsen has designed a clock that seeks to give a physical manifestation to the change of time through the growth of knitted material.

The circular knitting machine encased within the clock consists of 48 needles, a thread spool, a thread holder and a roll of yarn. Moving in clockwise direction, one day leads to a complete round, while a year gives users 2 meters of a complete scarf.
