This picture is part of a posting on a blog called Why the Mona Lisa's eyes follow you around. The blog is part of a collection of blogs that can found at ScienceBlogs.
I always imagined the painting Mona Lisa was significantly larger.
I still would like to see it, but at least now I will not be caught off guard and feel that initial dissapointment that it is smaller than I expected.
Did you know that Mona Lisa has no visible facial hair at all - including eyebrows and eyelashes?
