Video installation art

In this chapter, the part the interested me the most was the video installation that involved viewer participation; viewers are not only audiences but also a part which created the whole art piece. After reading this part, what I understanded was viewers and the installation art here was making a cycle alternatively. With the help of surveillance technique, it's like a "mirror" that you can recognize yourself and it can recognize you also in the surveillance installation art, "you" and the art piece can not be separated from each other.
Many of Bruce Nauman's works represent these kind of art. I found one of his work, an exhibition shown in a gallery pretty interesting and has the same idea as the ones introduced by Rush. But Bruce Nauman used hundred of fish instead to produce this piece. 
"The spectacle resembles something dreamed up by Magritte, a vision of fish swimming in the air during a heavy rain produced by the fish themselves"--The New York Times. The fish were hanged and filled the whole room, "swimming" in the water that pumped out from themselves, and that was also a "cycle" that similar to the idea I found out earlier in Rush's article.
