Today my brother told me about a similar project, from a few years back, that I ought to check out. The project, “Feelings” (2003) was an interesting affair. Composer Robert Wallin and artist and programmer Simen Svale Skogsrud had made a piece where the audience of a short video wore a simple EEG sensor while watching. The readings from the sensors were used to compose music using Wallins unique fractal formula. The audience could after the viewing ask to have their “personal soundtrack” burned to a CD.
