As much as it can be shown that shadows obey the simple laws of optics, there is something elusive about their appearance. They are part of our environment, but they appear and disappear from our sight; they are elusive and mutable. We tend to conceive of our world as stable but with shadows it is different because they do not seem to belong to the real world. We cannot touch or grasp them. What if we are merely shadows? Mere spectators of this world? Shadows among shadows? 'Spectators' opens to this creative provocation.
