A sequence from Stereoscope, an animated short film with sound, by William Kentridge. Courtesy of the artist and Marian Goodman Gallery, New York. The film will be shown at the Newport Art Museum through March 10. This is the eighth installment of Mr. Kentridge’s decade-long film series about the character Soho Eckstein, who represents the archetypal white South African businessman of the post-Apartheid era, and is also often interpreted as an alter ego of Mr. Kentridge, who says, "I have never tried to make illustrations of Apartheid, but the drawings and films are certainly spawned by and feed off the brutalized society left in its wake. I am interested in a political art, that is to say, an art of ambiguity, contradiction, uncompleted gestures and uncertain endings."
