Well, this isn’t really the work of Christo and Jeanne-Claude (or if it is, they’re keeping pretty quiet about it), but there is a fabric-covered cylinder where my town’s water tower used to be. There was some hissing noise coming from the direction of the tower once the curtain went up — the tower was taking a shower, perhaps?
Also, the fabric itself does present some aesthetic enjoyment as it rippled in the wind and as it was partially highlighted by the sun.
My suspicion is that this fabric was put up merely for practical reasons, but I like to find art wherever I can find it. (See other Ogle County unintentional art here.)
