  OpenKnit is an open-source, low cost, digital fabrication 
  tool that affords the user the opportunity to create their 
  own bespoke clothing from digital files. Starting from 
  the raw material, the yarn, and straight to its end use, 
  a sweater for example, in about an hour. Designing and 
  producing clothes digitally and wearing them can now  
  happen in the very same place, rewarding the user with 
  the ability to make decisions regarding creativity and 
  responsibility.

Thanks! I can't believe I hadn't seen this yet.

I actually have a knitting machine, which works similarly, but haven't used it much. Short programs are way more appealing than counting pins by hand.
