Or what about Poros by Nathan Cravan, which is actually a window (those bits of light you see are actually the trees, lawn, sky outside--and this is not a great photo)?
And then there is arrythmia by Chung Im-Kim, a piece that suggests a quilt because it uses industrial felt that is made of blocks silk screened (with a pattern based on an electrocardiogram) and hand stitched together.
This exhibit implies that the MFA is answering the question in favor of the label art, but the exhibit also suggests that such labels become meaningless in the large gray area between the two. Many of the items in the exhibit play with your perceptions so that you are forced to see the world just a bit differently and that is always a worthy experience. And several of the works were created using CAD programs and 3D printers, another direction artists are taking and the art world will have to get used to.
And, to be fair, the MFA already places such works as one of El Anatsui's magnificent metal quilts made from found materials in the contemporary art section, but still they maintain a contemporary crafts gallery that houses such gems as this little sculpture made of wood, Familiar Strangers by Betty Scarpino.
Unequivocally art, in my opinion. But that is the point, I guess: The use of the two terms is opinion and only becomes an issue when a particular piece or medium is excluded from a show simply because of the labeling process.
It's a beautiful, thought-provoking exhibit and, if you're still reading, thanks for the company!
