The Second Triad Coloring Book by Harry Turner
	In 1974, my father created the Triad impossible object. His designs travelled across the Atlantic and one of them was featured in Martin Gardner’s column in Scientific American. Then Dover Publications of New York commissioned a book about Triads consisting of an explanation of how to create them wrapped around “32 Plates To Color”.    My father was struggling with cataracts when the book was published in 1978. A generation later, when Dover decided to reissue the work as a colouring book without the explanation pages, it seemed a good idea to suggest a follow-up based on my father’s vast body of later work. I helped him with a synopsis and sent it to Dover but, despite several reminders, we heard absolutely nothing more from Dover.    Long after my father’s death in 2009, I found a partial draft of a second book of designs, and some further ideas. It seemed like a good idea to complete the project on his behalf. Philip Turner, 13th April 2013.
