Ever a sucker for knitting and geekery, I was intrigued by an article I found on DVICE:
The Music Technology Group in Barcelona has devised a process to measure a person’s brain waves, and create a custom scarf with the pattern. The team asks a person to wear an EEG cap, and listen to about 10 minutes of JS Bach’s Goldberg variations. While this is going on, a computer is measuring the resulting brain activity, and then transferring it into a knitting pattern with an open-source machine called Knitic.
Not only is this super-cool, I’ve now answered the question of what to buy the person who has everything.
