Fractal modelling of real world images

Mankind seems to be obsessed with straight lines. I am not sure where it all began, but I like to imagine two Druids overseeing the construction of Stonehenge, and using a piece of stretched string to check the straightness of the edges of those huge stone rectangular blocks, or the path that the light beam from the equinox sun would follow. It was at least an efficient form of quality control; for very little effort by those two Druids it kept the laborers with their eyes sharply on the job.
