Artist duo Varvara Guljajeva and Mar Canet teamed up with a Barcelona-based brain researcher named Sebastian Mealla to create NeuroKnitting. The team hooked a knitting machine created by the artists up to an EEG recording, which measures electric pulses from the brain.

Users listened to the aria and seven variations of Bach’s “Goldberg Variations” while wearing an EEG headset in order to measure different levels of relaxation, excitement, and cognitive load in response to the music. The data from the EEG was sent to the Knitic machine, which translated it into a two-colored pattern. 

The resulting scarves are unique visualizations of people’s physical and mental responses to music.
