Look at this article. They have dressed up and digitally manipulated four people to pose as their famous ancestors have in original portraits. Like they show a painting of King Charles II of England and next to it the ninth times great grandson of Charles II in the same pose and digitally reproduced costume. This is great fun and an interesting idea.
