Not what I was expecting, but good. We just saw the exhibit at the Venetian and I wanted to learn more about him.
An interesting look into the history of the Vitruvian Man, Leonardo's life, and some of his methods. He had such an interesting, varied mind, and his greatness often got in the way of his successes. His journals show a glimpse into how his fascinating imagination led to designs of inventions, ideas, and great works of art.
Read this if you want to learn more about Leonardo, but don't let this be your only source about him.
