This one is absolutely amazing.  The elephant is made mostly of wood and operated by over ten puppeteers using a mixture of hydraulics and motors. Weighing as much as 7 elephants, a replica was built in Nantes France in 2007. (w/pics)

A spectacle on a huge scale, this is one of the most stunning shows ever. 
The elephant was created by the Royal de Luxe – a French mechanical marionette street theater company.
