I am doing the Da Vinci Project along with you. I have been looking through dozens of images from the notebooks and haven't been able to settle on just one or even three. As a musician, I am drawn to Leonardo Da Vinci's ideas about music and his designs for musical instruments. As a political scientist, I am drawn to his war machines, as well as to his work as an advisor to warring Italian princes. I can't do it all. I have to make choices. I also know that my choice may evolve a bit as I flesh out what I want to do.
