‘Dazzling’ is a good way to describe Alyson Shotz’s optically enticing sculpture whether it’s the shimmering curtain of Fresnel lenses she memorably installed in the Guggenheim’s atrium in ‘07 or a mirrored fence hidden in plain view in the fields at the Storm King Art Center. ‘Wavelength #2’ from 2008 continues Shotz’s interest in waveforms and uses dichroic acrylic to both transmit and reflect different wavelengths of light, creating a range of colors from a clear material. (‘Wavelength #2’ is at Paul Kasmin Gallery as part of ‘Sculpted Matter’ through August 17th.)
