I had checked that site from IGN yesterday, I really didn't get what was going on, but I have to admit, for MS/Bungie, this is a really damn clever and subtle way of generating "buzz."
EDIT: Well, I really didn't *look* at the website, so to speak, I just looked at the picture of the website. It would seem to be a really clever way of generating buzz. But still, 25 days from now, that would only be August 23, sometime around 5 AM EST. That's definitely not when the game is coming out, so it must be something about the game itself? Perhaps this is what IGN was talking about, a new race added to the Covenant, like a race of bee-aliens or something.
Hmm, "In 12 days this medium will metastasize." That's weird. Maybe the website for whatever this is will be out then. Hey, maybe it'll be a demo for Halo 2!!!!!
