Kara Walker's work explores the raw intersection of race, gender, and sexuality through iconic, silhouetted figures. Walker unleashes the traditionally Victorian medium of the silhouette directly onto the walls of the gallery. In recent works, the Walker uses overhead projectors to throw light onto the walls and floor of the exhibition space, implicating the audience through their own shadows. Kara Walker's is featured in the Season 2 episode "Stories" of the Art21 series "Art:21 -- Art in the Twenty-First Century".

Mark Bradford transforms materials scavenged from the street into wall-sized collages and installations that respond to the impromptu networks—underground economies, migrant communities, or popular appropriation of abandoned public space—that emerge within a city. Bradford's work is informed by his personal background as a third-generation merchant in Los Angeles and by the traditions of abstract painting developed worldwide in the twentieth century. Mark Bradford is featured in the Season 4 episode "Paradox" of the Art21 series "Art in the Twenty-First Century". For more information: http://www.art21.org

LED display of some of Holzer's "Truisms" at the Indianapolis Museum of Art. Sorry it's a bit shaky, it was hard to hold my camera steady. Oh, and it's better to watch it muted because the only sound is just obnoxious background noise from the museum.
