I found this on an interesting site called Neatorama
Industrial designer Siren Elise Wilhelmsen made a clock that knits a 2-meter scarf over the course of one year. It’s called “365″, and its purpose is:
[...]to give a physical manifestation to the change of time. drawing from the change that is witnessed through the growth of human bodies and hair, the same concept is found in ‘365′ which translates time through the growth of knitted material. the clock houses a circular knitting machine with 48 needles, a thread spool, a thread holder and 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.
