Actually quite neat and tidily done, though the lettering a little 'off'. Clearly a shout-out honoring The Lady herself, Lol!
Here's quite a good watch by Richard D Hall.
I find a couple assumptions here and there regards complex crop circles being mostly 'man-made' because they are more "mechanical" in design and show board-marks... However, given the part on John Lundberg, for example, and his 'CircleMakers.org' website (approx 40.00 mins in) tied with possible MI5 connections, I'm inclined to believe much of the disinfo program is to make genuine crop circles appear to be man-made via deliberately leaving evidence of board-mark 'stomping' before anyone else arrives at the seen - made all the more possible given MI5 help/involvement and their subsequent links with the military of which a
非常strong presence in prime crop circle country (Wiltshire particularly) - and no doubt having access to high-tech capability to when a crop-circle is in the process of being formed and therefor the advantage to always being the first to know its location.
(FWIW I personally believe the very impressive 2001 Milk Hill 'Galaxy' formation (30.20 mins) is in fact man-made... The relationship and spacing of circles don't seem quite perfect enough to me even when taking in consideration any dips in the landscape)
