"Thomas Schrunk's work is characterized by the changing luster from the surface of the materials used. The areas of relative bright and dark change as the viewer walks (or drives) by, or with a change in the angle of the light source. His pieces are found in the collections of princes and presidents, Steinway Art Case pianos, celebraties, charitable organizations and fine residences on three continents. He works in a variety of media, teaches, writes in trade publications, has several patents and patents pending, and is the inventor of "lustrous concrete", a method of creating light-responsive (lustrous) imagery on opaque materials.
Photography will give a basic impression of the size, shape, and color of the work, but with lustrous materials it gives only a single viewpoint. The actual light response from the surface changes with a change with a change in position of the viewer, or a change in the angle of the light source. Single photographs of lustrous materials are really akin to a still from a movie. Several video clips are on the site to give a better understanding of the effect.
