L'idée principale d'un luminarium est d'offrir au public la possibilité d'une expérience sensorielle unique suscitée par la beauté des couleurs et de la lumière.
“It isn't an isolating experience. In Antwerp, where the structure occupied a public square near the city centre, a dear old couple slowly ambled past me. Meanwhile, a younger pair waxed lovey-dovey on the floor, and children rolled around. Plenty of people roamed about, pleasurably lost, smiling with wonder, delight and, who knows, perhaps something approaching contentment. I sat down, leaning against a rounded wall, and others soon followed my example. Unwittingly, I'd helped create instant community. The public square had moved indoors.”
