Describing the important roles of industrial design, graphic design, architecture, vintage neon and mid-century icons in his work, Robert Mars has gallery globe-trotted from Tokyo to Munich to Germany, and now Atlanta. Opening today, Art Department Gallery presents his latest collection, DIAMONDS AND RUST. Mars captures the independent aesthetic of the not-so-distant past that's been replaced by homogenized corporate culture and standardized cityscapes. He employs layers of color, subtly collaged printed matter from the 1950s and 1960s, and stark, black imagery. Capturing the once poetic and now nearly lost highway strips of the American past, you don't want to miss these paintings and icons that are now signs of desperation and ruin. Through April 30. Free. Opening reception, 7 p.m.; Mon.-Wed., hours by appointment; Thurs.-Sun., 5-11 p.m. 327 Edgewood Ave. 678-732-0068. www.artdepartmentgallery.com.
