Stewart Kranz, "Interview with Woody Vasulka." Science and Technology in the Arts: A Tour Through the Realm of Science/Art. New York: Van Nostrand Reinhold Co. (1974): 281-82.
In this 1974 interview, Woody Vasulka describes his evolution from documentary filmmaking, via multi-screen projections, to the electronic medium of video. He states, "The kinetic portion of the image is more important than the image itself... The whole gate to it was the signal." Vasulka describes his fascination with the electronic medium, which he finds so vast that it is like "a universe that has never been explored."
