This sculpture encapsulates an experimental phase of Bertoia's work in the early 1940s while still at Cranbrook. Fascinated by the effects of light, Bertoia created a structure in order to suspend triangles of metal to reflect and restrict light when the sculpture was placed in front of a window. The first examples were painted with a white palette, and "the gradation of values that the light imposes on the forms creates a varied pattern" (Nelson, 28). Bertoia painted one side of this sculpture in a range of blue tones, infusing the piece with a brilliance rarely seen in his work. These early works "...formed the basis of one of his major concepts out of which later grew a group of important sculptures" (Nelson, 28) including the sculptural screens for General Motors Technical Center (Detroit,1953), Manufacturers Hanover Trust Co (New York, 1954), and Lambert Field (St. Louis, 1955).
