We've all seen metal sculptures that are unbelievably cool. UK sculptor Stephen Kettle's 1.5 ton slate sculpture of Alan Turing located at Bletchy Park in Britain stands as a testament to the time it takes to create such amazing works of art. The Alan Turing piece took a total of 18 months to complete. His other sculptures consist of figures, busts, animals and other objects like the one featured below.
