Time. It's an old topic. From cave paintings to code paintings, the recording of time is among the most basic and persistent of subject matters seen in art, and it has very often propelled new tools for keeping itself measured. Oddly enough, despite time's catalyzing role in the innovation of techniques and technologies, time-based media has all too often been left out of exhibitions surveying creative explorations of time. But the current exhibition at Dundee Contemporary Arts, entitled "Timecode," takes the pulse of temporality from a more electronically enlightened perspective. The show does include works employing painting and sculpture, but puts them in conversation with works such as Thomson & Craighead's "narrative clock," Horizon (2009), in which webcams around the world convey a perpetual horizon, and Tatsuo Miyajima's large-scale LED timepiece, Counter Void S-1 (2003). Situated next to classic performance works by the likes of Douglas Gordon and On Kawara, and of course the eponymous multi-channel film by Mike Figgis, the show holds a lens to the myriad ways in which time endures as an organizing principle for our lives and our creativity. - Marisa Olson
