"The crop circle formation at Avebury Manor seems to depict our solar-system (not in proportional scale) on December 21, (+/-) 2012 - the highly debated end of the Mayan calendar (or at least one of the most prominent interpretations of that date). Whatever this means and who-or-whatever created this crop circle, I do not know - but the basic message of it is quite clear."
