Derivative rubbish.
Nearly half a century earlier, Dinsdale Pirhana blazed a stellar trail in this medium back in the 1960's and 70's.
From memory, Vince Snetterton Lewis and Stig O'Tracey were two of his earlier accomplishments.
As site specific installations, their heads nailed to the floor, they did not attract much public attention until featured on BBC TV's 'Monty Python'.
Perhaps the apogee of his work is to be found in his tenderly crafted 'Mrs O' Tracey- Head Nailed to a Coffee Table'.
