While wandering around Piazza del Popolo, I happened upon a wonderful exhibit celebrating the Genius of Leonardo Da Vinci. The exhibit consists of a movie depicting Da Vinci as he comes up with some of his most interesting inventions and paintings. Though it was in italian, I was able to get the gist of most of it and found it quite interesting. There were also about 50 machines built to scale from his original drawings and notes. For 7 euro I spent a couple of hours learning much about this amazing man's thought process. The exhibit is from May 4, 2011 until April 4, 2012. If you have the opportunity to take it in, I wholeheartedly recommend it.
