In the Transformers movie trailer between :37 and :39 the frame shows "Sector Seven Org" at the top and "Takara 83" at the bottom. If you go to SectorSeven.org and type in takara83 as your password you are treated to a screen full of mess. It looks like a person's desktop and clicking on the exclamation mark on the dock brings up a video sequence where a Lt. Col. Powers talks about discovering a "blip." Beyond that we have no idea what's going on. Go forth puzzle-loving ARG folks and figure it out.
