2008 Barbury Castle crop circle: pi solved?

Some have stated perhaps some of us are way over thinking this, and you know what, they're right. What do we know about it? It's a crop circle (made by man or something else, we don't really know for sure). It's Pi. It was "formed" 3/4 of a mile East of Barbury Castle in Wiltshire, England (Wiltshire is known for being a CC hotspot). The first digit of PI starts facing East.

Well... since we know the obvious meaning is PI, why include the other 3 outer circles? What do those mean? What is their relationship? What do they have to do with the price of tea in China?

Hey guys, Jerusalem UFO hoaxers or aliens - who knows - tied their last video to this crop circle.

What meaning might it have with this new info? Could just be a random reference to entertain us, but maybe someone's trying to tell us something...alien or not.
