There is a logo to click on Geek Dad talks about it
HereI thought I was onto something with "Triskaideka" -- greek for 13, or Unlucky 13. But the other file was named 'SRCVR215 --- guessing 'Shadow Run Cover 2 of 15'.
So, other than the files having a clue in the name -- so far there is no pattern...that I've seen yet.
There goes my productivity for the day!

Thanks guys!!!
Seriously, though - thanks! This is a really cool idea - give kudos to whoever thought it up!
