The word artist is such a loose term I think it is difficult to positively label any activity as "art." I'm sure everyone has seen a fair share of paintings hanging in museums or galleries that we would have a hard time labeling as "art." I don't think I would ever feel comfortable calling myself an artist because the term has always seemed a little pompous to me. On the other hand, I've never been under the impression that the word itself requires that the activity be devoid of chemistry and physics. Seems a little silly.
