This is just a stab in the dark but would it be possible to take the seperate quadrants and layer them on top of each other to create a message? Like maybe the white fading lines will crosshatch and create a message if you place quadrant 5 over quadrant 4? I'm really bad at this puzzle stuff but I just want to try to help, Mike has been so excited about the artwork for this new album and now I can see why. The government is about to start using thi method for C.I.A. Messages.
