"Best known for the politically charged images he has projected onto buildings and monuments from New York to Warsaw--images of rockets projected onto triumphal arches, the image of handcuffed wrists projected onto a courthouse facade, images of homeless people in bandages and wheelchairs projected onto statues in a park from which they had been evicted. In projects such as the "Homeless Vehicle," which he designed through discussions with homeless people, Wodiczko has helped to make public space a place where marginalized people can speak, establish their presence, and assert their rights."
Wodiczko give participants the opportunity to speak about their traumatic experiences, creating spaces for individual therapy and public reflection. I saw I saw the documentation of the Tijuana Projection that was part of the Open City exhibition at Eyebeam. The aim of this project was to give voice and visibility to the women who work in Tijuana's "maquiladora" industry. The women's testimonies focused on a variety of issues including work-related abuse, sexual abuse, family disintegration, alcoholism and domestic violence. A headset with a camera and a microphone was connected to two projectors and loudspeakers that transmitted the testimonies live, on two consecutive nights, to an audience of more than 1500.
I remember that when I saw it last year it was a bit strange because the way the image and personal histories were recorded created a very intimate space but they were exposed in a huge projection.
I think that is very interesting the work he is been developing by creating several "psychocultural prosthetic equipments". Take a look of some of his work at the Interrogative Design Work at MIT
Besides his public art installations, Wodiczko also developed a series of vehicles for homeless and immigrants that " function, not without a touch of irony, as implements for survival, communication, empowerment, and healing." They provide this social group with a ‹street tool› that responds to basic necessities of survival economy such as living, sleeping and washing, as well as collecting and reselling cans and bottles.
