As far as someone "appropriating" Mondrian, that is, I think, impossible.
And this impossibility is quite interesting. Mondrian, from around 1920 on,
is no longer an "author." Thus there is nothing to appropriate. He was
involved in a school called "the style," the object of which was, ideally at
least, to produce a totally anonymous art. He encouraged this, and became
upset when certain members of "de styl" deviated from his way of doing
things. There are, in fact, already a great many "Mondrians" painted by
others. Once, when given some advice in speeding up his extremely
painstaking methods, so he could be more productive, he answered: "I do not
need more paintings. I need to understand." I think Mondrian would be
extremely pleased that yet another artist would be interested in using his
approach. And, as a friend of Duchamp (there was mutual admiration here),
he would probably have understood her "need" to exactly duplicate one of his
paintings (if this in fact is what she has done). In any case, in my view,
Mondrian's work is undeconstructible, or, let us say, at least as
undeconstructable as that of Derrida.
