I encountered a minor problem when coming to photograph the skull for my front cover. The skull I had in mind from a model skeleton in my school's Biology lab had been decapitated by a group of rowdy pupils using the room as a dressing room for the school show, a number of years previously. However I found a skull which I believed to better than this; a slightly smaller scale skull in the same lab.

 The darker colour appeared to be almost crystalline, similar to that of the Crystal Skull in the 2008 film "Indiana Jones And The Kingdom Of The Crystal Skull", which makes the skull appear far more mystical and given the ending of the film, sinister.
