Braid: Flags

Skimming through a thread, I found the following (credited to Derbonk);

On a different side note: David Hellman (the creator of all the visual art) wrote a great series on his blog about the art of Braid, I hope you have all read it already, it's really interesting. He also hints that there might be something up with the flags in front of the castle. So, I looked at them and they do look like those signal flags you can see on some ships. Looked that up on Wikipedia ( http://en.wikipedia.org/wiki/International_maritime_signal_flags ) and here is the result:

World 2 (blue/white small checkered) means "N - Negative"

World 3 (red/white checkered) means "U - You are running into danger"

World 4 (yellow/black checkered) means "L - In harbor: The ship is under Quarantine/At sea: You should stop your vessel instantly/With four numerals, latitude/Inport: Radiological Hazard"

World 5 (blue cross on white) means "X - Stop carrying out your intentions and watch for my signals"

World 6 (yellow and blue thick stripes) means "K - I wish to communicate with you. With one numeral, I wish to communicate with you by; 1) Morse signalling by hand-flags or arms; 2) Loud hailer (megaphone); 3) Morse signalling lamp; 4) Sound signals. Inport: Man Aloft.
