I think the best course of action for tomorrow would be:
1. Keep trying to decipher the morse code, and any other messages in the .mp3
2. Figure out which cipher, if any, the arrows down the side of the page use
3. Find out how the numbers "12" and "20" that derived from the source code maths problems fit into the puzzle
4. Try and fit it all together and hope for some hints from Ed
Well done on everything so far guys, you da best
