A Wire sculpture of a pig can be seen here as it evolves - but this could just as easily be  dog, cat, wolf or tiger or - anything you want. 

 

Lots of wire, time and effort. 

 

The final part of the process is to dip the pig in molten zinc to galvanise it and then etch the surface with an acid to give a lovely aged patina - this prevents the sculpture from rusting.
