Seeing the unspeakable : the art of Kara Walker

Artist Kara Walker has used silhouettes in a pioneering and innovative form to express social and political commentary about sex, race, violence and injustice. Initially some images appear to be recognizable, and others may look like Rorschach tests, but all of the silhouettes demand closer inspection. Viewers are never unmoved by Walker's art, with favorable and unfavorable criticism which crosses race, class, gender and age.
