While working with some of the pioneers of holography, Dan created a special spotlight that was used by Soho's Museum of Holography to light holograms. The related field of holography led to Dan's interest in lenticular art and, in turn, after nearly a decade of research and experimentation, to the creation of his "Motion Viewer," his third patent in that field and the inspiration for Safari and the other Photicular books.
