It is an irony of contemporary aesthetics that accessibility is not considered a virtue. A degree of alienation between the general audience and the creator is a given, and a work of universal appeal is suspect. Any creation that is an uninhibited celebration of color, shape, and motion would go begging in a world of minimalist forms or conceptual constructs. Humor as a quality is particularly suspect. Alexander Calder not only produced work based on these elements, he made the first mobiles as a young artist in Paris.
