I've given up on trying to figure it out. I guess I just can't think in the way required to discover what the chuffing hell it means.
It's not even really about thinking. I mean, I utterly suck at all forms of puzzles, yet I managed to blunder my way into the solution of this one. A few of your earlier posts sounded like you were on the right track. It seems like you understand the relation to what was at the end of the Halo 2 trailer, which should give you a basic idea of exactly what you're looking for. You know that it has something vaguely to do with how Hard Light functions, even if it's something that no one really thinks about on a daily basis. And I managed to sneak that word "structure" in there, too. If all else fails, and you feel like going more of a brute-force route, remember that I said that a completely-unrelated discussion in the recent past was what gave me the final clue. In retrospect, I now know why the person who prompted said discussion did so.
And terran_emperor, it might be a bit helpful to think about how some of these possibilities you're proposing could work in any real sense. I don't see how knowing a particular RGB value could be of any practical use, nor would knowing which number moderator Colonol Dekker is...other than maybe begging him to give you the answer.
Again, look at the trailer, think about how it relates to what the Halo 2 trailer did, and go from there.
