For ten years Ray Zone has been presenting 3-D slide shows on the history of 3-D in photography, motion pictures, art, science and popular culture at different branches of the Los Angeles Public Library system. Each program is projected on a large silver screen and the audience, consisting of children, teenagers and adults, views the three-dimensional images wearing polarizing glasses similar to those used for 3-D movies. Below are dates and locations for Ray Zone's Library 3-D Slide Programs for 2005.
