I watch sci-fi, not all of it - as most is dross - and for the most part I enjoy it. I sometimes play computer games, I am thinking of games such as tomb raider (why didn't they call that game 'grave robber' by the way? They should do...) I enjoy films like Indiana Jones occasionally; as a child of the 80s, it is pretty much obligatory that we have seen them. I do, however, have a question: has humanity, at any point in history actually made a temple that reacts to filtered light by having to move mirrors so that they align and focus light on a specific point? It always seems that the puzzles of those films/games are built around the premise that ancient civilisations always do temple architecture around the way in which light will be refracted around and about. Has this happened ever? Or is it a common, simplistic, ploy by lazy script writers who can't be arsed to think of any other action by a mystical race? Has anyone else noticed any stupid ploys in these sorts of films?
