By staring into seemingly abstract fields of colour in this book, 3D images materialise. This is made possible by the remarkable power of modern computers, and the use of the 'Salitsky Dot', a patent-pending image-rendering system that takes 3D viewing into the twenty-first century. It is rather like learning to ride a bicycle: some people get the hang of it right away, others have to work at it for a while. In this book the images have been arranged in the order of complexity, with the easiest ones at the front. Easy-to-follow instructions are included.
