the automaton and the id
"The duck had over 400 moving parts, and could flap its wings, drink water, digest grain, and defecate. Although Vaucanson's duck supposedly demonstrated digestion accurately, his duck actually contained a hidden compartment of "digested food", so that what the duck defecated was not the same as what it ate. Although such "frauds" were sometimes controversial, they were common enough because such scientific demonstrations needed to entertain the wealthy and powerful to attract their patronage. Vaucanson is credited as having invented the world's first flexible rubber tube while in the process of building the duck's intestines. Despite the revolutionary nature of his automatons, he is said to have tired quickly of his creations and sold them in 1743." [wikipedia]
