Once it is out of his hand the artist has no control over the way a viewer will perceive the work. Different people will understand the same thing in a different way.
Sol LeWittWhat the work of art looks like isn't too important. It has to look like something if it has a physical form. No matter what form it may finally have it must begin with an idea. It is the process of conception and realization with which the artist is concerned.
