It seems to be a mailbox that's been recently opened.  It says a bunch of numbers around the bullseye, the top numbers read "29.9218, -90.1126", whatever that means, and the bottom reads "-0020:10:6:21:04:02" (I know it says 24 in the animation, but that wouldn't make sense, just, trust that it is 21 and not 24).  You have no idea what these numbers mean, but you notice that inside the mailbox is a familiar book, coloured green, with a bright green title.

Bored with the computer, you move over to the other side of the pickle.
