Adelheid Mers first became known for multicolored light projections, but since 2000 she's been creating some of the most original art I've seen--large digital diagrams that elucidate ideas in books that have engaged her. Three untitled diagrams from her series "Images After George Lakoff: Moral Politics--How Liberals and Conservatives Think" are now on view at the Page Brothers Open Studio. One compares Lakoff's notions of the "ideal liberal" and "ideal conservative" using simple icons and text: citizenship requires either "fearless responsibility" or "fierce patriotism." Mers pushes art's boundaries by immersing the viewer in abstract concepts, but the aesthetic dimension is here too: the colors in these elegant poster-size works are echoed in the different-colored tulle pom-poms hung around the room, which connect colors to thoughts--and thought to light. She also acknowledges her own biases in this pointed election-year show; another diagram includes concentric circles on the left that take up much more space than the hierarchical ladder on the right. Page Brothers Open Studio Project, 179 N. State, through September 12. Hours are noon to 6 Thursday through Saturday; the closing reception is noon to 4 Sunday, September 12; 773-368-0377.
