Firefox branding promotion?

I like Firefox, I use it as much as possible, but now someone with faaarrrrrr to much time on their hands has taken the promotion of the Firefox brand just a little too far... Crop Circles? I ask you!

As I said, too much time on their hands. Well, the "they" are the Oregon State University's Linux User Group, and it is summer time. What more needs to be said?
