Series 3

 To my mind these images resemble   both flowers and explosions, both of which are interesting metaphors for dreaming processes. These are all five-minute dreams, representing 300 data points. If you look carefully you can see that each jagged outline is just that of the ordinary biowave, except that I have bent it around in a circle. Two EEG waves create the first two “petals”, while EOG and EMG form the inner two. Colours are determined by age, gender and the relative harmony of the waveforms – anomalous data gets a more anomalous colour.
