Crop Circles Unrelated to Aliens: Report

Crop circles or crop formations are among the most intriguing mysteries known to man. None of the many theories presented so far have gathered enough majorities, though the one that says extra terrestrial beings are responsible for these 'designs', seems more convincing. However, a report that appeared in Physics World now claims that crop circles are not related to aliens. Large, complex designs depicting a myriad of images, each defined by perfect symmetry of shapes, crop circles are now being attributed to be the brainchild of a skilled mathematician. What else could explain the sheer brilliance, and the precision with which points in the below image were plotted? 

Mathematical genius?

The report further goes on to describe that unlike earlier when tools like wood planks, bar stools, ropes, etc were used to attempt these crop circles, the technology used today is far superior. Crop circlers are using microwaves to make stalks of corn fall over, and cool down in the same position (horizontally). 

The mystery surrounding these crop circles, however doesn't end, here. Just recently, a 200ft crop circle appeared mysteriously, beside the equally mysterious Stonehenge, only cementing the belief that crop circlers are active, and in action.
