Da Vinci doodles brought to life: Leonardo's genius on display in hometown museum

The main attraction of the Leonardiano Museum, in Vinci, Italy, is a model of a self-propelled vehicle based on a drawing that Leonardo da Vinci created in 1478.

"We think Leonardo probably designed it to move according to a pre-set course at a royal court, perhaps to cause a sensation for a visiting king from outside Italy," said Romano Nanni, the museum's director.
