First, there was cow poetry:
[Nathan] Banks, a 22-year-old student at Purchase College, painted single words (from "a" to "existential") on the flanks of about 60 cows near his upstate New York home, then let them wander around to see if they could compose poetry.
So Holsteins and Jerseys named Elsie and Maggie came up with phrases like "eccentric art," "performance as cow environment" and Banks' own favorite, "organic conceptual art as poetry."
So what's the point of this, then? Fortunately, as with the poetry itself, the cows provided the answer:
"There was a big concern that the cows would be stressed and give less milk," Banks said. [Cow owner] Gerry Ruestow said milk production actually went up a bit, "probably because the cows were a bit more active. The cows were as interested in the observers as the observers were in the cows."
Once you have cow poetry, the next logical step is - you guessed it - sheep poetry. The benefit here is a bit more abstract and metaphysical:
[Artist Valerie] Laws, 48, said: "I like the idea of using living sheep to create a living poem, and creating new work as they move around.
"Quantum mechanics is a branch of physics which a lot of people find hard to understand, as it seems to go against common sense.
"Randomness and uncertainty is at the centre of how the universe is put together, and is quite difficult for us as humans who rely on order.
"So I decided to explore randomness and some of the principles of quantum mechanics, through poetry, using the medium of sheep."
