As if by clockwork

I have just watched the most amazing program on clockwork life like models from the  1700's  . A child like manikin that could write and a moving swan made of silver . Some machinists even studied human body parts to find the most life like method to mimic how we move . Incredible . What you have to remember is some of these machines are over 200 years old . Today thanks to micro-chips and circuit boards we take such movement for granted .......
