There is a 7-minute projection in a 360 degree domed ceiling above. Each viewer is outfitted with a set of electrodes, which gather brainwave data. This information is instantly transformed into visual imagery, in real-time correspondence with the actual activity of the brain, and projected onto the screen: Six undulating bio-amorphous cells represent the left and right lobes of each of the three participants' brains, and a waving line moves in correspondence with blinks and other facial movements.
This instant biofeedback thus incorporates the experience of watching the projection, and the interaction between the three viewers. The forms change shape and color in response to three types of brainwaves, showing which type is most dominant. Alpha (blue) waves indicate wakeful relaxation, Beta (pink) waves indicate alertness or agitation, and Theta (yellow) waves indicate a dreamlike state. When the two cells come together, that demonstrates "coherence" between the two lobes of the brain. Mental functions such as thinking in other languages or doing maths problems immediately transform the characteristics of the graphics.
