Boomerang (1974), is a video by Richard Serra in which the artist taped Nancy Holt, as she talks and hears her words played back to her after they have been delayed electronically. Because of the delay, Holt finds it very difficult to talk and even think. In Serra's words, "[This] is a tape which analyzes its own discourse and processes as it is being formulated. The language of Boomerang, and the relation between the description and what is being described, is not arbitrary. Language and image are being formed and revealed as they are organized."
