Creating three dimensions

I was amazed by the ingenuity and the impact of these portraits. It led me to think of the infinite numbers of ways to exaggerate dimension. While the use of the bas relief of nails or the convincing painting alone could create this effect, together they are more powerful. In combination they give both a visual and tactile experience. In the often planar world of jewelry pieces--it is exciting to ponder the ways to take advantage of new ways to create the illusion of depth.
