A theory I briefly entertained but I don't think I posted about was that Ricky was jotting down notes about such things as Movies. Some movies that came out around the time of his death that can be found in one form or another in the text are:
South Park: Bigger Longer and Uncut sprk and uncut clearly appear in the code.
I have seen some others but I am curious if anyone else sees this. I quickly moved on from this but thought I would revisit it here.
