The idea was to have people behaving more relaxed in a certain environment. The lamp reacts to audio so anything that makes sound causes the lamp to react by dimming down and slowly fading up again. Thereby ‘correcting’ your behaviour. Because the signal was very strongly amplified even the slightest movement could set off the lamp.
Another version of the program requires sound to turn the light on. So people that dislike the dark are forced to continuously produce sound.
