I stole your idea. http://evilaerosolcan.gamerdna.com/i...ned2ivi4ug-jpg. Something I noticed when I saw the thumbnail. It looks like an image of a sphere, kind of. With something hanging off the bottom. And the things on the left and right look like side views of the middle thing. I'm not sure, that's just what I see. As far as what it is, or how it may be significant, I don't know.
It just hit me: the dots are just a blown-up floor plan of Ironforge. compare the pattern to one of the pictures of the city. It's possible that there's something hidden in the dots, something we're supposed to look at in a certain area of the city...but I won't know until I take an even closer look.
