An interactive exhibit featuring life-size models of Leonardo da Vinci's 500-year-old inventions and machines is opening in New York City's Times Square.
Although best known for painting the masterpiece Mona Lisa, da Vinci also designed a fantastical array of futuristic flying machines, robots, weapons and mechanical devices.
Highlights of the exhibit opening on Friday include the Great Kite flying machine, a working prototype of his Self-Propelled Cart, and physical models of his mechanical bat and lion.
Visitors also can use touch screens to turn the artist's sketches into three-dimensional models.
Leonardo da Vinci's Workshop runs through March at The Discovery Times Square Exposition.
