Kenneth J. Dunkley of Camp Hill, Pennsylvania, discovered two points located at the periphery of a person's vision that, if obstructed, cause an ordinary picture to appear three-dimensional. This discovery led to the invention of three-dimensional viewing glasses (3-DVG ) that achieves 3-D effects without lenses, mirrors or optical elements of any type (U. S. Patent # 4,810,057). Dunkley has conducted visual effects workshops for four years at the Museum of Scientific Discovery in Harrisburg, PA. During this time, two major articles on his invention and his workshop appeared in Stereo World magazine, a primary source of information for 3-D photography enthusiasts in the USA. Another article appeared in the SPIE Proceedings, a scientific publication for 3-D topics. Ken Dunkley's reputation as a visual pioneer surpasses the patented 3-DVG invention. He is a leader in the field of art holography where, in 1973, Dunkley created his hologram entitled "Thoughts."
