Krzysztof Wodiczko (born April 16, 1943) is a Polish artist renowned for his large-scale slide and video projections on architectural facades and monuments. He has realized more than 80 such public projections in Australia, Austria, Canada, England, Germany, Holland, Ireland, Israel, Italy, Japan, Mexico, Poland, Spain, Switzerland, and the United States.War, conflict, trauma, memory, and communication in the public sphere are some of the major themes of an oeuvre that spans four decades. His practice, known as Interrogative Design, combines art and technology as a critical design practice in order to highlight marginal social communities and add legitimacy to cultural issues that are often given little design attention.He lives and works in New York City and teaches in Cambridge, Massachusetts, where he is currently professor in residence of art and the public domain for the Harvard Graduate School of Design (GSD). Wodiczko was formerly director of the Interrogative Design Group at the Massachusetts Institute of Technology (MIT) where he was a professor in the Visual Arts Program since 1991.
