What is conceptual art?
Sometimes referred to as Conceptualism, this is an art form where the idea(s) or concept(s) behind the work take precedence over material concerns and traditional aesthetics. Many conceptual artworks can be created by anyone simply by following written instructions. The concept or idea is the most essential aspect of the artwork.
