Most complex crop circle ever discovered in British fields – Telegraph
This is apparently the mack-daddy of crop circles. Frankly, I’d want to check on the whereabouts of students from any nearby University math departments the night the circle was made.
That said, it is nice to think that if aliens were truly using crop circles to communicate with humans, they would try and impart something basic and supposedly universal, like the first 10 digits of pi.
