Sun Dog, 1976. Solar and laser installations for the U.S. Bicentennial Expo Science and Technology, Kennedy Space Center, Cape Canaveral, FL. Commissioned by the National Endowment for the Arts. In 1976 Sun Dog was the first work of art ever commissioned by the National Endowment for the Arts.

Sun dogs are a member of a large family of halos, created by light interacting with ice crystals in the atmosphere. Sun dogs appear as two subtly colored patches of light approximately 22° to the left and right of the Sun.

"On Cape Canaveral, where the moonship gantries stand beside the feeding grounds of heron and pelican, the National Endowment for the Arts has commissioned a work that attempts an even closer blending of technology and nature. This is Sun Dog, by Rockne Krebs, a sculpture in light that uses both lasers and, when the day is clear, sunbeams.

The enclosure for the Canaveral piece is a temporary geodesic dome, one of many constructed by National Aeronautics and Space Administration to house exhibits at the Bicentennial Exposition of Science and Technology. The dome measures more than 30 feet high in the middle, more than 80 feet across at ground level, and consists of a thin rubberized tarpaulin linked to an aluminum framework."
