''Angle of Incidence'' is a spiral/helix/waveform sculpture that hangs approximately 25ft. high in the atrium of the ARC building. The spiral is made of aluminum square tubes, laminated with dichroic acrylic on all sides. The bars will be 2.5'' square and varying in length in 2.5'' increments, from 68'' to 128''. The intervals of length of the bars get smaller then grow larger again as they reach the middle. The structure mirrors itself on the other side. Therefore, the spiral is not left or right handed, it is a combination of both in one.
