The visitors brain waves of different states of consciousness are scanned by a headset. A live-monitoring of this neurofeedback controls the colored space illuminations. Each color shows the present attention and concentration level. Once the visitor succeed to achieve a high (= meditative) brain wave frequency, he activates the UV-illumination which visualizes a large, fluorescent image of the universe.
