I thought Marina Abramovic's piece called Rest Energy was very inspiring. The name of this art work "Rest Energy", is based on a relativity theory. In this theory it is stated that there is an equivalence relation between mass and energy. Both the man and woman in this sculpture are resembling one piece of this. I enjoy this very much because this woman is Marina and the other side of the arrow is being held by her lover/husband. This theory is expressing that in order for something to work both sides need to share the same amount of energy unless it will not work; symbolizing that in this exercise the two people are testing their trust, and if they are not balanced someone can get hurt. I thought Rest Energy was a brilliant idea.
