Six paintings in the Uffizi that you can see up close (online)

Have you ever felt terribly irritated by the greenish protective glass in front of Botticelli's Primavera and Birth of Venus? Or have you never had the opportunity to see Caravaggio's Bacchus or Bronzino's Portrait of Eleonora and her son Giovanni in person? See these works virtually and in high definition for free until January 29 2011 on the website haltadefinizione The Primavera is reproduced at 3000 times the resolution of a normal camera in a file that contains 28 billion pixels - not too shabby! You can see single brush strokes when you get up closer than could ever be possible in the museum (or generally with the naked eye). There's also Leonardo da Vinci's Annunciation and the Baptism of Christ by Verrocchio and the young Leonardo.
