I agree with all the comments above too, starting with Caveman's. There have been just a - so far as I know - very small minority of simplistic crop designs produced by people, and that tended to be early on such as the 1980s. I think early groups who "revealed" themselves were attention-seekers who really hadn't produced that much.
It'd be impossible for people to create this and many other past designs just overnight ... never, apparently, using lighting (!), and never ever being found-out. There's never at all mentioned the slightest residue of people having been there either such as footprints when originally discovered, so far as I know.
It is mysterious indeed, since if it were an attempt at communication - as we think of it - it plain isn't working as it just leaves us baffled.
If they're reading this with their super-duper powers, I suggest they just write in a large field: "Make Love, Not War!"
Or maybe "Elvis Is With Us" to reassure us they have a sense of humour!
The phenomenon is all probably UFO-linked but I still don't think that's 100% confirmed. Or just one race of them doing it?

Oh, yes! Of course! It's a cube!

Maybe it's an attempt to ruin the grain harvest. Of course, if it is to drive us to starvation, it's a bit unnecessary. We're doing very well on that score for ourselves.

Initially, looking at the design marked in the crop, I thought that the designs on the outer edges of the cube were arrows, around each side of the cube. Each arrow being comprised of 4 'lines'.
BUT THEN. (This is interesting) Looking at the diagram of the design from Venetian link:
...it seems to me, that they aren't arrows.
Imagine the design in 3D: a cube comprised of 216 cubes (6x6x6), The 'arrows', seem to delineate 3D hollow cubes around the outer edges of the main cube . Do you (everyone:)), see what I mean?!
So then, if this is supposed to represent a 3D design, that means that the cube (cubes) are enclosed inside a sphere. Maybe the circle that is shown as not being concentric to the main outer circle, is moveable within the outer shell of the overall sphere? A moveable sphere within the main sphere (?)
EDIT: I've just thought - If the cube was made up of smaller solid cubes - they would be visible through the hollow outer-edge cubes - so maybe the main cube is hollow, with 'squares' (cuboids) central to the each side.
(? Although the 'squares' on the bottom would be visible from this angle - and yet they aren't pictured....hmn? Maybe they didn't want to complicate things :D)
It really gets you thinking doesn't it. Such as the non-concentric circle...? Not suggesting this is definitely the purpose, but many designs "get you thinking" - in the past they've represented many things, such as chaos theory.
