Clock Knits Time Into a Scarf. 365 is a real, live clock by Norwegian-born, Berlin-based designer Siren Elise Wilhelmsen. For every day that passes, the clock knits a row; after a year, it whips up an entire 6.5-foot scarf.
How it works: The machine’s face has a spool of yarn hooked up to a pair of needles that Wilhelmsen programmed using an Arduino board to knit a single mesh on the half hour. When the scarf reaches its full length, you just pop in a new spool. (via fastcodesign)
