Looking at the updated website. I'm not sure I really like the idea of making the Weyland Corporation this tangible, touchable entity with answers. In some ways it's better and more interesting to have the faceless evil.
Just don't pay the viral stuff too much attention then. I doubt there'll be too much of this sort of detail in the movie, the idea is just to drum up interest.
If that flickering star isn't morse code then it's damn well trying to lead us on a wild goose chase, because it's on a loop (I think) and the pattern fits entirely with morse code. It also stops blinking all together after a while.
I'll be damned if I can get much though. Not sure why but I'm finding it very very hard to keep track. The ones I'm surest of (and I don't know where they come in the sequence) is a 5 followed by an L. That's come back consistently every time I've tried to keep track.
More to follow no doubt, and of course this could easily be a wild goose chase even if it IS morse code!
