Through February 3 - Rafael Lozano-Hemmer: Frequency and Volume at SFMOMA. A lingering remnant of the 2012 ZERO1 Biennial, this installation by Mexican-born/Montreal-based artist Lozano-Hemmer very effectively melds technology and participation. As you move across a darkened room your projected shadow picks up a series of radio frequencies while the size of your silhouette determines the volume of the broadcast. Lozano-Hemmer, whose installation of motion-tracking fluorescent lights you might have recently experienced in the exhibition Field Conditions at the museum, has made his process visible by installing his radio equipment in the gallery just next door to the projection room with artfully-hung ceiling cables leading you out to the fourth floor terrace right to his radio tower itself. As I stood there in the exhibition picking up mysterious maritime communications and something labeled "Space to Earth" with my body I thought of the judge in Kieslowski's Red and his illicit (and seductive) habit of listening in on other people's phone conversations. I also really enjoyed watching other people play with their own shadows and in one case dance lithely across the length of the entire gallery.
