Who -- or what -- is responsible for the thousands of complex patterns found in cereal crops all over the world?

Are they all made by hoaxers?

Are they made by aliens or Government satellites?

Are they screams from a dying planet?

Are they manifestations of human consciousness?

Is there an esoteric code hidden in their patterns that comprises a message for mankind?

Are we in danger, and are crop circles some kind of warning signal?

Or are they all created by natural earthly causes -- magnetic fields, underground water, plasma vortices...rutting hedgehogs?
