Brook Kobold, 17, of Discovery Bay, holds the big scissors as she poses for a photo along with other students before the unveiling of a mosaic wall along Brentwood Boulevard in Brentwood, Calif., on Tuesday, June 3, 2014. Liberty High School's Public Art and Design Academy unveiled the mosaic wall on Brentwood Boulevard Tuesday. This internship is a three-year process with Liberty seniors putting dozens of hours of work to plan and create a public art project each year. Liberty High has the only public art program for high school students in the state. So far, they have created an aquatic mural, painted agricultural themed utility boxes and now the mosaic wall.
