When he said Nitro should know the answer, I instantly checked out the ascii code sheet for those letters, but I'm too stupid right now to figure anything out -- I've been drinking way too much and my IQ is sitting around 70 right now. Nitro is the key to the puzzle. We all know that Nitro, of all people, would be the one to program the matrix. So perhaps there is some meaning in computer lingo. I did a search on google and nothing came up. I know it is cheating but that's how I got through my entire life so why stop now.
See what happens when you over-analyze? I was about to break out matrices, calc, code-breaking algorithms ... man.
