Just found this while playing around in Google Maps My Maps feature. A 67 metre Firefox logo as a crop circle.
Its been around since August 2006 and apparently it’s not the first of such stunts by a Linux user group at Oregon State University. When they do a job they do it properly, – they went all out with helicopters and planes documenting the process.
Link to the groups site.

Have you tried firefox’s seo tool…
Yeah, Go OSU
That’s abviously fake, whoever made this set a drop-shadow instead of an inner-shadow, and the opacity is all wrong, you can’t see any of the underlying structure…
Other then that, it’s a pretty nice idea
If this is fake, why does it show up on the real google maps?
