Notable Works
Schwartz used the works of Leonardo Da Vinci extensively in experiments with computers. One notable work she created is Mona/Leo, for which she compared the image of a Leonardo da Vinci self-portrait with the Mona Lisa, matching the two faces feature by feature to show their underlying structural similarity. Specifically, she replaced the right side of the Mona Lisa with the flipped left side of a red chalk self-portrait of Leonardo. Superimposed lines drawn on the image showing the close alignments of the bottom of the eye, eyebrow, nose and chin prompted her to argue that the Mona Lisa is in part a cryptic self-portrait of the artist. In further experiments along these lines, she removed the gray tones in Leonardo da Vinci's self-portrait and superimposed the Mona Lisa eye over it. Not everyone is convinced by her argument for the identity of Leonardo da Vinci and the Mona Lisa; one common counter-argument is that the similarities are due to both portraits having been created by the same person and therefore bearing the hallmarks of a characteristic style. Additionally, though the drawing on which Schwartz based the comparison is held to be a self-portrait, there is no firm historical evidence to support this theory.
In a similar experiment, Schwartz used a custom ray-tracing program to investigate the perspective anomalies in the drawing of da Vinci's fresco painting of the Last Supper. Her 3D computer-generated model showed that the perspective lines in the Last Supper do match up with (extend) the architecture of the refectory of Santa Maria delle Grazie in Milan where the fresco is located, but only because of certain changes Leonardo made to standard linear perspective.

Famous quotes containing the words notable and/or works:
“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when it’s more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (1894–1963)
“‘Tis too plain that with the material power the moral progress has not kept pace. It appears that we have not made a judicious investment. Works and days were offered us, and we took works.”
—Ralph Waldo Emerson (1803–1882)
