I appreciate your skepticism, its all good as long as we are investigating the issue!!

They are definately getting more complex! This has brought up some ideas about what crop circles are, like a communication.
One such idea is that we were just getting basic info from crop circle formations at first, and now its getting more technical. Its really very exciting.

"Know, oh, brother...the study of intelligible geometry leads to skill in the intellectual arts because this Science is one of the gates through which we move to the knowledge of the essence of the soul, and that is the root of all knowledge'"
- From the Rasa'il by the Brotherhood of Purity

The formations are "sacred geometry", which is the unchanging basic way that mathematical relations and mathematical explanations of all living things can be expressed. The way we can take a circle and dissect it to find the radius is a start, but more interesting are things like the musical scale, which moves up in pitch in a mathematical way that is, for some reason, pleasing to our ears - just a few Hz different, and it sounds bad. Each note is mathematically separated from the next one up or down in a presice way. These relations are found in crop circles!!

More complex then is the way cells interact, the way calcium reacts with cells for eg., and there are "sacred geometry" relations there too, precisely as a musical scale.

Amino acids, protien folding - this gets very complex, but is still following mathematical relations, some of which have equations that we have yet to discover. Just as humans are learning this "more and more" , so is it that crop circles are getting more complex over the years. I cant wait to see what this crop circle season brings us!!

I might not be explaining that very well, so here is a quote from one of the links in previous posts:
"Our experience and our reaction to all things beautiful is made possible by our unique ability to subconsciously recognize geometric order from transitory chaos. At this level, the perfection inherent in a Greek temple or a painting by Da Vinci is not simply because it is made of a particular material or hue but because the harmonic proportions contained in their design are bound by the laws of sacred geometry, which is itself the embodiment of harmonic waves of energy, melody and universal proportion. What our senses respond to is the geometrical and proportional harmonies and wave forms created through the application of sacred geometry."

K - We DO "get it" when we look upon crop circles, something seems pleasing about these formations- the shapes are connected to our sub-conscious somehow, we "recognise" them as something familiar to us...

So the crop circles getting more complex means two things:
-the communication is getting more specific, like at first they were about the shape of a machine, and now they are about the engine in it.{CCs may be instructions for a new technology]
-humans are becoming more 'able in our awareness', and CCs reflect this ability by being more complex.

Of course, I don't know a thing for sure. A lot of this is about having faith in nature to be able to deliver messages to us, sub-consciously or in diagrams.
What I can be fairly sure of is that the message is getting deeper and the time when we will know something FOR SURE about them is getting nearer!
