Sunlight moves, and artist Larry Kirkland has used it to create one of the most popular public artworks in Scottsdale. He carved the shape of a bird into the roof over the entrance to the Scottsdale Library. As the sun moves across the sky, the bird appears to move across the interior of the roof over the entrance. I photograph both the roof carving and the illuminated bird as they came together late in the afternoon. (The artist also created a huge golden feather of gilded aluminum that is suspended over the entrance. Your can see my image of it at: http://www.pbase.com/pnd1/image/113688088 Both the bird and the feather make up a two-part work of art called “Imagination Gives Us Wings.”)
