Several years ago I was asked to have a cast made of my head for a project.  The details are unimportant - the artist gave me the plaster cast and my husband often referred to it as a "death mask."  A few months ago I had the pleasure of meeting mosaic artist Linda Zeien, http://skullsaics.com.  I asked her if she would be willing to take on my "head" - she did and the results are above, Josi Under Glass.  Check out her website - her work is brilliant!
