Thu Illuminatorz

So I was enjoying the post from TXB re: The Popcorn Swindle, and I clicked on the picture for a bigger view. Well, what do I see on that banner, below the JeffCo dealy-o? Some faded, obstensibly motion-picture-themed, symbol. But, I dunno, methinks it has traces of Masonry. Could I get some help from my brothers and sisters on deciphering this? I think the horizontal purple/blue lines are definitely reminiscent of Illuminati. No doubts.
