Personal identity is defined by ideas and mental processes generated in the brain in the form of electrical currents and voltage fluctuations, with frequencies and speeds that cannot be interpreted visually or by manual methods. The neural cortex activates in different regions of the brain, depending on external stimuli and internal processes, making their interpretation even more difficult.

Raw EEG data creates a circular system of multicoloured particles that highlights the fluctuation in brain activity. Inner Waves is an abstract representation of basal electrical currents in the brain.
