Novel Program Can Be Read in Dark Theater

What good is a program in a darkened theater during a show? No good, decided an English inventor, so he developed a semitransparent program which theater-goers simply hold up so that light from the stage or moving-picture screen is behind it. Outlines of the printed matter on the program thus are silhouetted so that they become readable, regardless of how low the theater lights are turned.
