SET AND OFFSET TRIANGLES 1997, measures 72"x 84"x 8".
The first layer consists of two rows of triangles pointing down. In the second layer two rows of triangles again appear, they are reversed, pointing up and appear tilted slightly to the right. In the third layer the rows of triangles point upwards, but appear to tilt instead slightly towards the left. Each triangle is constructed with one 90 degree angle. When the layers are assembled together, they create an illusion of two rows of wedged tetrahedrons with a constantly vibrating tip.
