Wodiczko is most well known for his over 40 large-scale outdoor projections, which have been installed in over a dozen countries. His works are usually socially conscious, and often political in nature. Examples include projections onto buildings of hands or faces of people who speak about personal experiences or crimes they have suffered, allowing the public airing of issues usually kept private. He has labeled this style of art Interrogative Design. His most well-known installation took place in 1985 when he projected the image of a swastika on the South African Emabassy  during a protest march in criticism of the country's aparthied system.  A controversial project of his was the design and construction of a special cart for homeless people. After consultation with homeless people in New York City, the cart could be used to transport a small number of belongings, provided space for the collection of bottles, and could be used as a primitive shelter.http://www.pbs.org/art21/artists/wodiczko/
