Krzysztof Wodiczko, artist, professor and director of art, design and the public domain at Harvard Graduate School of Design is renowned for his large-scale slide and video projections on architectural facades and monuments around the world. He uses images and voices of the homeless, immigrants, survivors of domestic violence, war veterans and other marginalized people in his work. His interrogative design practice, begun in Poland and continued at MIT, creates nomadic instruments for homeless and immigrant survival, communication, empowerment, and healing. Wodiczko’s socially engaged art practice entails forging trusting relationships with veterans, and giving voice to the voiceless so that they can speak about the unspeakable.
