Doing da Vinci

2009 NR

Renaissance man Leonardo da Vinci didn't limit himself to painting and sculpting: He was also a prolific inventor, leaving behind notebooks filled with designs of myriad weapons of war -- some of which are re-created in this Discovery Channel series. An industrial artist, an engineer, a carpenter and a special-effects designer join to turn da Vinci's designs into working devices, including a circular armored tank and a three-story siege ladder.
