We went in to the permanent exhibition of Leonardo’s machines. This guy was awesome, his insatiable appetite for knowledge and desire to make life easier for people (including the military) led to his designing the first prototypes for so many things we are familiar with today (500 years ago!) The ball bearing race, lifebouy, helicopter, bicycle, washing wringer, army tank, machine gun, and odometer to name a few.
