Erwin Redl’s large-scale light installation Nocturnal Flow presents itself as a sea of LEDs stretching from floor to ceiling of the University of Washington’s Allen Center. Composed of over 10,000 individual light units whose intensity varies through time, the grid-like work serves both to emphasize the verticality of the space in which it is housed, but also to accommodate a natural motion birthed from sterility. The use of environmentally-reponsive sensors also imbues the work with a streak of subjectivity, as it can be perceived in contrasting ways depending not only on angle of view, but also time of day or year.
