I recently stumbled across an amazing artist who works solely in slate! The nature of the shape of slate creates stunning visual effects in terms of shadow and light. The image shows Alan Turing, who “did more than any other to make possible the breaking of the German Enigma codes at the secret Station X at Bletchley Park in Buckinghamshire.”.
On his website http://www.stephenkettle.co.uk, Stephen explains that the process takes a great deal of time, an average of 60 hours per week! He goes on to say that this process can not be speeded up as this would compromise the quality of the work. Due to the flawless nature of the work that he produces, I can hardly blame him.
