Art is an open term. It assumes the impossibility to coin a concrete definition, although there is no need for this art. We can explain the variability of art only by way of capturing the very essence of its indefiniteness. Art can speculate about its reflections of the world and react to the history that made it what it is. Ambiguous perception leads us to break free from the frames of conventional reception and allows us to see what Alice discover on the other side of the mirror.
