I don't usually post stuff on crop circles, as fascinating as they are, because since so many English Tossers think it's amusing to hoax them, the field (no pun intended) is even more fraught with false leads than the rest of UFOlogy.
But this one was pretty interesting. You can see two flashes of light, and then if you look closely, some dark things of some sort moving around in the field.
The setup for filming was pretty sophisticated, using 4 IR cameras for parallax, and then another dude went and filmed the same area during the daytime to make sure that it matched up. An intricate, 'woven' crop circle was discovered in that same spot the next morning, with the wheat apparently interleaved like a basket!
Check out the videos (there are several) at the link in the title...
