Contemporary art comes to us in all shapes, sizes and conceptual bent and utilises any and all materials that the imagination and technical ability of the artists allow. There are no rules governing how to make and present a work of art and no particular intellectual or conceptual restraints. However, there are a couple of words which are safe to use to describe artwork if it is going to have significant and lasting impact. One is quality and the other is nature. Without a high degree of quality in conception, execution and technique the works will largely fail to hold our attention and without some relationship to nature there is a lack of resonance for the viewer.
