Keith Sonnier's light installation Lightway makes an important contribution to the visual appeal of the Munich airport. It exhibits an impressive combination of functionality and attractiveness that is characteristic of this facility. As a source of light and an aid to orientation, Sonnier's work serves a concrete practical purpose in directing travellers along their way. At the same time, the light sculptures installed on the walls parallel to the moving walkways possess a suggestive aesthetic aura that fascinates and captivates the observer. The rhythmic sequence of colored light engages in fruitful interaction with the continuous motion of the walkways. The equally gentle and intense bath of light has both a stimulating and relaxing effect on passengers. This book brings the extraordinary interplay of light and color to life for the viewer in brilliant color photographs complemented by construction sketches.
