take a look at this:
http://www.alexpetty.com/2009/11/09/starship-schematics-in-the-crop-circles/
the two crop circle patterns when taken, added into a 3D CAD
environment and rotated 360 degrees about the vertical access in the
3D CAD environment generates what looks to be a drawing for starship
that uses a torus based (rodin coil type technology) anti-gravity
drive.
