"A Cantor Arts Center team led by undergraduate chemical engineering major Ivy Nguyen discovered minute traces of pigments that originally covered the original sculpture but were washed away by the millennia. Nguyen's team used 3D rapid prototypic technology to create replicas of the artwork, which is painted to look as the sculpture did in ancient times. Credit: L.A. Cicero"
