Well I'll throw in my 2 cents.
Lately these have mostly represented constellations, especially ones "reminding" us of 2012. The object is to create a collective consciousness of fear, thus fueling the machine. They can't survive without our fear, evil literally feeds off fear.
In this case I lean towards Trapper's a**ho*** with satellites explanation.
My first impression was being very underwhelmed by this formation - it seemed to be unbalanced and did not resonate with me at all.
Some crop formations do... they are beautiful and complex, usually depicting sacred geometry or something of that nature. You feel something harmonic in them even though you don't know what it means. The 2012 ones feel inauthentic to me. A similarly dissonant-feeling formation was the one with the alien message in it and the cartoon alien face. Really?
So at any rate I think (this is just my intuition) that our military is mimicking authentic formations to perpetuate the 2012 doom propaganda.
Simple formula for truth:
evil = fear
goodness (in whatever form) = love
