I agree that we haven't found anything meaningful yet, but I do think there is something in there. When we figure out the right thing to do (whether that's 3D glasses, use of the physical component, or whatever), I suspect the meaning will be obvious. Vague hints at lettering, whether actual or the result of pareidolia, are not how we're going to solve this. There's something we're meant to do, and we haven't done it yet. We may not even have the tools we need. It could requires something that will be revealed tonight at the show, or something from the Add Violence physical component.
