Check out this website:
Circlemakers.org.
There are a hundred crop circle sites on the "space brothers" theme. Damn few like this one. I'm going to check out their book.
I believe those making the crop circles really believe they have a symbiotic relationship with those studying them. One reason they play "coy" about the whole thing. Revealing all the operations clearly and with documentation would be a lot like bringing the kids down Christmas Eve and showing them Mom and Dad eating the cookies.
As it is, both sides are having the time of their lives.
