The Wonderful Wizard of Oz was published in 1900: http://en.wikipedia.org/wiki/The_Wonderful_Wizard_of_Oz I really should have talked about it before. It was very popular, and no doubt it would have influenced the design of anything robot-looking. Any robot would like or unlike the Tin Man, no doubt, so this is my little homage to it. I will have to read it, probably, to get a grasp of the language and the culture of those days
