Yin-Yang

A yin-yang optical damage image inside a glass. Gray images are the front and side view of the glass with the balance provided by a Canon digital camera in front of a plasma computer screen. Blue images are placed in front of a computer monitor as a light source and analyzed with a cross-polarizer. Carlos Trevino, David Iturbe-Castillo and Sabino Chavez-Cerda, Puebla Pue, Mexico
