In large-scale slide and video projections on architectural facades and monuments, Krzysztof Wodiczko explores the relationship between art, democracy, trauma, and healing. In countries all over the world, Wodiczko has projected images of the faces, hands, and bodies of local community members onto the built environment, accompanied by the voices of marginalized citizens, activating public space in his examination of human rights. Born of a Jewish mother who fled the ghetto in World War II Poland, Wodiczko is concerned with the impact of war and violence on individual lives, and aims to use his art to “break the code of silence, to open up and speak about what’s unspeakable,” as he says. He also produces what he calls “Instruments”, objects made collaboratively to facilitate the survival, communication, and healing of homeless people and immigrants. His Homeless Vehicle Project (1987–89) is a one-person mobile shelter designed in collaboration with members of the homeless community.
