I've posted on the art of automatons before. Here are a couple more fascinating videos.
[from the description] "Swiss artist François Junod has changed the automaton into a new art form. He calls his unique creations androids - mechanical robots designed to resemble humans in both appearance and behaviour. swissinfo visited his studio in St Croix, in the Jura mountains."
This 7 minute piece is entirely in French. The machines are exquisite.
