This Is a Camera Which Shoots This (1995)

"This Is a Camera Which Shoots This" and "As I See You You See Me" are both set up facing two cameras and monitors and the performer walks between them while voicing the sentence of the title. Here the words "This" and "You" have the same form in the nominative and the objective cases, switching the roles of not only the signifier (word) but also the signified (object).
