By shining white light on a glass slide stippled with millions of tiny titanium dioxide nanopillars, researchers at the National Institute of Standards and Technology and collaborators have reproduced with astonishing fidelity the luminous hues and subtle shadings of "Girl With a Pearl Earring," Dutch artist Johannes Vermeer's masterpiece. The approach has potential applications in improving optical communications and making currency harder to counterfeit.
