Who, indeed, does care. I suspect these examples is,like all art, a personally defined truth. So I went on a search. Wikipedia states "Art is an application of a creativity that has some form of appreciative value, usually on the basis of aesthetic value or emotional impact. Much about art is controversial, including what specific cases can be considered such."

The tinman gallery says "I have defined art as the creation or invention of linked and sequential pattern which extends over all aspects of the composed field. This definition builds a strong link between the concepts of art and composition."

Aperson I know believes photography is not art because it's"just" capturing something that already exists and not "creating" anything.

I'm beginning to believe art is dynamic and cannot ever be defined.

In the end we alldefine art for ourselves and arguments over the definition is like grading a subjective answer to a subjective question.
