Mona Lisa Smile

Now it's official: Mona Lisa was 83 per cent happy, nine pc disgusted, six pc fearful and two pc angry. That's the conclusion of a University of Amsterdam computer that applied "emotion-recognition software" to Leonardo da Vinci's work, the British weekly New Scientist reports in next Saturday's issue.

The algorithm, developed in conjunction with the University of Illinois, tries to assess the human mood by examining key features such as the curvature of the lips and crinkles around the eyes, then makes a score with respect to six basic emotions.

I dont think she looks 83% happy in that painting. Do you?
