Puzzle Box Package

Zen at Halo Wars Heaven<ref>http://halowars.heavengames.com/key</ref> received a package in the mail. (Possibly, other people have received similar packages?) It consisted of a puzzle box containing a note and USB key. He has posted a Flickr photo set of the box and contents.

The letter says:

You are now a decoder. There are only a few like you, but thousands more are looking for you. Find the other decoders before Zero Hour. Go to www.vanishingpointgame.com

A spectacular adventure is on the horizon.... can you find it before it disappears?
-L
P.S. I've hidden something in a puzzle box for you. Find the box, find a way to open it?

The header says "From the desk of Loki..." and the footer says "ENIGMA DIRECTOR."

The whole note looks like it was printed out of an inkjet printer. The box it came in has a return address of
LOKI
One Microsoft Way
Redmond, WA 98052

The USB key contains a puzzle grid image (see: Keys) and a video: http://vanishingpointwiki.com/media/vanishingpoint.mp4
