Signs

I'm not given to X-Files-ish, "The Truth Is Out There" theorizing, but I thought this was pretty interesting.

A crop circle appeared in a corn field in Corcelles-pres-de-Payerne, Switzerland last weekend, and nobody seems to know how it might have been made.

I've seen news segments on how people made crop circles England, but this one seems beyond the capabilities of those methods. Just how does one make a crop circle like this?

Here's the Swiss news story on it in English.

Update: Unfortunately, that link doesn't work. Try this link to a Fox News story about it, and then follow the link in that story to the Swiss news item.
