I must cattily remark here that my favorite bit is this:
"It was Lewitt who said that if you want to make art about an idea, you have to pick the simplest form and repeat it until the form loses meaning and the idea becomes the art."
which is something Eaton repeats a lot when interviewed. What I cannot make out is what the idea she has is, which idea is becoming the art.
Is her idea the idea that the idea becomes the art? So by repeatedly photographing cubes the idea of the idea becoming the art becomes the art? Not to put too fine of a point on it, that's ridiculous. Maybe the idea is something more abstract, something that can't be put into words, but a) she never seems to say that, always referencing Lewitt and leaving it at that and b) I certainly do not discern any such thing in the pictures.
Doesn't mean it's not there, of course.
