Just joined this site to get in on this gknova6 thing. I just want to say you guys are brilliant for figuring this stuff out. It's truly interesting! I was up all night last night reading the threads for both channels! I also have a few theorys/ideas about this though they are likely irrelevant.
The coordinates on the one part of the Kryptos cipher are the same as the ones that where on the SOMD coordinates for the CIA location.
The guy who made the Kryptos sculpture, Jim Sanborn, wrote a book called Atomic Time. On the cover there is a clock with hands pointing near 6, possibly something to do with the 6 in gknova6.
I heard something about the Trinity Bomb on here. The trinity a symbol. Treyarch's symbol is a trinity.

Again, this probably is irrelevant, but thought at least I'd share some stuff I found.
