In the Eye Filmmuseum in Amsterdam I saw a very interesting exhibition "If We Ever Get to Heaven" by South African artist William Kentridge (1955). In the first room you saw some portraits painted on cardboard.
Than you entered a dark room where you could see a frieze of moving images measuring some 45 metres in length. The people were carrying the images from the first photo on an endless parade.
The numerous figures form a collectively kaleidoscopic picture of people on the move. These are images that hit us every day through the media, of people fleeing from hunger, war and sickness.
The procession evokes their sadness yet also conveys their vitality. Accompanied by a repeting music it was a very impressive expierence. You can read more about the exhibition here.
