Even inside a gallery, these pristine glass sculptures by American artist Roni Horn subtly change as the light from the skylights passes through them. Their title references dreams while their surfaces resemble pools; they’re objects to transport you. (At Hauser & Wirth Gallery through Jan 11th. Check website for holiday season opening hours.)
Roni Horn, Untitled (“A dream dreamt in a dreaming world is not really a dream…but a dream not dreamt is.”), solid cast glass with as-cast surfaces, 10 parts, unique (series 5), 2012.
