Basically Trent Reznor (of Nine Inch Nails) straged a really elaborate and cool game regarding his new album. The article goes into details, but basically there are hidden clues and such that were seeded on concerts shirts, on flash drives that were left in concert bathrooms, in songs, etc. These could then be followed to tell a story. It's some really cool stuff. The article, in proper fashion, is seeded with similar stuff.
