Unfortunately, Dr. Chunlei Guo of the University of Rochester hasn't yet figured out how to turn scrap metals into gold, but he, along with Dr. Anatoliy Y. Vorobyev, has
discovered how to colorize a variety of metals. By utilizing a "femtosecond laser processing technique," the duo has crafted a method for turning even aluminum into aluminum with an impeccable gold finish. Furthermore, they've also been successful in turning tungsten dark blue, leaving reason to believe that nearly any metal could be altered to appear as a different color. Ah, just imagine what these folks could do with your MacBook Pro.
