The centerpiece of Sabrina Raaf's installations and photos at Klein Art Works, Searchstoretrash, is an engaging reminder that art can also be fun. The viewer sits in a chair facing a monitor and holding a remote control that moves a tiny vehicle with a video camera along an elaborate 150-foot roadway that loops along one wall of the gallery. The vehicle's journey is tracked on the monitor--a goofy mix of low and high tech that's mirrored in other works. In Another Soft Landing a separate looping track meets the wall, then continues as a drawing--a reference to the illusory nature of art making. In the photograpic diptych Suburban Particle.1 a woman floats in a bathroom as if she's conquered gravity, and in the photo Suck, Spin, Weave a man who appears to have devolved into a spider uses a machine to collect his belly-button lint and spin it into a web to catch the women in the adjacent photo, Twice Caught. These other works helped me see that the technical imperfections of Searchstoretrash--the video reception can be poor, the vehicle's treads can come off--offer an implied critique of virtual worlds, which may be why I preferred maneuvering the little car while watching the roadway rather than the monitor. Klein Art Works, 400 N. Morgan, through October 17. Hours are 10 to 5:30 Tuesday through Saturday; 312-243-0400.
