I thought I'd share this here; My friend gave decoding the morse fully a whirl and it's pretty much accurately transcribed I believe (ignore the workings out above). It was done from the original file, but 1 or 2 letters may be cut off from the start and end as the morse was a bit muffled, but the main body of it is almost definitely accurately transcribed from the original audio file. The problem is, like everyone else's attempts it returns gibberish, and some of the shapes don't quite make sense. It doesn't make any sense when following it through backwards from the end either. So we have to wonder if it's a variation of morse or something along those lines, or perhaps the gibberish does need to be further decrypted. If anyone has an ideas with it feel free to use it and have a go; he apologises for the handwriting but not for the badass D.C comics notepad paper
Here's the transcript:

EDIT: So the OWI Twitter seems to think we've cracked the picture, does that potentially mean the arrows aren't relevant?
They also just linked directly to this thread and the Wikia. Hopefully that means more help incoming
