Someone hacked a knitting machine so that it knits your brainwaves!
From the FastCo.Exist article:
NeuroKnitting is an experiment that uses an EEG headset to record how the brain reacts to music. It then translates that data into a pattern that can be realized in yarn via a hacked knitting machine. Each participant listens to a section of Bach’s “Goldberg Variations” while wearing a headset which measures relaxation, excitement, and cognitive load. Those features are then turned in a knitting pattern that’s sent to a knitting machine and turned into a scarf.
Okay, pretty rad. But for my scarf, can I listen to some Queen?
