The sun sets on a field in southern England. When it rises again the following morning, that field has been transformed into an enormous work of art. A large section of the crop has been tamped into a pattern of circles, rings and other intricate geometric shapes. But who created it?

Or are they elaborate hoaxes perpetrated by savvy, talented and very determined circlemakers? Believers and naysayers each have their own theories, but the truth remains elusive.
