"STEPHEN LONG" "...functions almost like a piece of the landscape—continually reflecting the changes going on around it. 1600-feet long and painted red, yellow, and blue... at times the entire spectrum was visible due to optical mixing along the borders, and the painted colors were constantly in flux due to changes in the color of natural light. At sunset, for example, when red light was falling on the sculpture the blue stripe turned to violet, the yellow stripe to orange. Because the space-projection literally went beyond the field of vision, movement and aerial views also became particularly important."
