  • In response to your Da Vinci portion of the video, I took the guided tour of the Leonardo Da Vinci exhibit in 2006 at Chicago's "Museum of Science & Industry". One note that was pointed out over & over again was that Da Vinci intentionally put flaws in his blueprints so that potential thieves couldn't recreate his inventions. I'm not trying to take away from your video, but just thought you should know!
