Artist Charles Freeman, better known as Brother Boko, rescues fluorescent paint and black light from the dustbin of nostalgia in Southwest Arts Center's presentation of THE MYSTERY & MAGIC OF THE CIRCLE MAKERS, opening Fri., MAY 23. Boko is a Left Coast transplant best known for several murals throughout the L.A. area. He uses the bright fluorescent hues to render the mysterious geometric forms that have appeared in crop formations around the world on 3- and 4-foot circular canvases. As if the black light weren't enough to encourage mass tweakage, 3-D glasses will also be available to up the psychedelic ante. Through June 20. Free. Opening reception, 7 p.m.; Mon.-Fri., 9 a.m.-6 p.m. 915 New Hope Road. 404-505-3220. www.fultonarts.org.
