"In a feat of optical alchemy, Dr. Guo, a professor of optics at the University of Rochester, and Anatoliy Y. Vorobyev, a postdoctoral researcher, use ultrashort laser bursts to pockmark the surface of a metal in a way that is not perceptible to the touch — it still feels smooth to the finger — but that alters how the metal absorbs and reflects light.
The result is that pure aluminum looks like gold, and the appearance is literally skin deep." ~nytimes.com
