But Is It Art?

I heard a piece this morning on NPR about Christo's latest project. Apparently he and his wife are going to put up 7,500 "gates" of saffron-colored vinyl in New York's Central Park next February. I found NPR's coverage pretty balanced, although I did chafe a bit at one interviewee's patronizing dismissal of the project's naysayers as "so 20th century." (If you're interested you can hear the NPR piece here.)

I don't get it. How is this art?

In a broad sense, I suppose it qualifies as "a product of human creativity." But I don't see how it enlightens, educates, or edifies anything other than the surnameless Christo.
