What would Leonardo da Vinci upload to Facebook? After painting the Sistine Chapel, would he take a picture and post it to his Instagram? Would he put the Vitruvian Man in his Mobile Uploads Album? Would he tweet about the annoyance of his forced ambidexterity? And what would he select for the Mona Lisa's profile picture? For better or for worse, we present the Mona Lisa with a duckface, because it's a look we know well, are guilty of, and secretly love.
