Interesting markings

I am new to the forum (but not to reptiles) and I recently bought a new ball, it had (what I thought to be) a really cool marking right behind its head. An almost perfect circle :) I love finding shapes among their splotches and markings.http://36.media.tumblr.com/09fd20dde...d5co1_1280.jpg

I don't know if it's just me, but the picture is broken ):

I see it fine. I have a couple with a circle like that:)
