One ought to be a little careful with words like "nonrepresentational" which tends to get used as a synonym for "abstract", but it's not.
Koons animals are abstract, but representational, like Cubist paintings and so on. There are clearly objects from the real world that are represented by these things, although the representations are abstracted. Contemporary art is often, but not always, abstracted. It is sometimes, but not always, non-representational. It is almost invariably conceptual, in the sense that the idea is the thing that matters, the execution is secondary.
Eaton is non-representational, abstract, but honestly the concept seems to be lacking. In the piece on the front page, she articulates no concept beyond the business about "you have to pick the simplest form and repeat it until the form loses meaning and the idea becomes the art" which is so circular as to be slightly silly. Your idea is to repeat the work until the idea becomes the art? But.. where does the idea come in?
She is a hard worker, making an appealing thing at a rate that proves she can make more work, but not so fast that it floods the market and becomes un-special. She has a pretty good story to tell. So, she's got gallery representation and is presumably selling pretty well. Good for her!
Making these things seems to me the most boring job conceivable, but she seems to enjoy it. A bit OCD, maybe.
