Zawahiri's Creepy Lump: Piety ... Or Frustration ... ?

I guess Ayman bin Chatty -- oopsie, I mean Zawahiri -- released a new video Friday. He's got a smiling Zarqawi over his shoulder, makes the usual threats and yadayadayada.
For a good analysis, please click now to Whalid Phares' excellent comments on the
CounterterrorismBlog. However, let's turn to the important question, which is -- where is Zawahiri's lump these days?
You'll see in the above photo that it looks kind of like an S curled around a crater, and it's more to the right of his forehead now. In April, it was more front and center; you can click here to a comparisons of the travels of the
creepy lump on a chump! over the past year or so, with comparative photo's.
I read somewhere this week that the forehead callous was supposed to denote piety, since it's supposed to be formed by pressing your face to the floor during prayer.
Of course, slamming your head against the wall because you're afraid to leave the cave would also do the trick.
