Transformer Gallery’s “Flat File” is a reserve of unframed, two-dimensional works by artists, both regional and abroad, with no gallery to call home. But if “wall/paper”—a show of selections from this wayward lot—is any indication, orphans hardly equate to misfits. The fashionable technocratic compositions of Benjamin Jurgensen’s Mechanize Something Idiosyncratic series depict polygonal architectural forms, maybe even 3-D space itself, in a state of collapse. Andrew Kozlowski’s spare drawings look like New Yorker cartoons, with intentionally nonsensical punch lines—such as the ungrammatical sign over a waterfall that reads one bedrooms available. There’s clunky collage on the walls, which is the death of any works-on-paper exhibition; fortunately, other pieces in the flat file itself (on hand for the curious collector or curator to browse) make up for any shortfalls of the show. The exhibition is on view from 1 p.m. to 7 p.m. Friday, Jan. 18, and Saturday, Jan. 19, at Transformer, 1404 P St. NW. Free. (202) 483-1102.
