so do we know any thing extra? e.g. is it connected to a film thats coming out? or is it just a short film by students or something like that?
That would kill the entire enigma.
All I notice is small and probably not much important stuff. E.g. I think that all of the newspaper headers read "What happened" in different languages. "Tango, Yankee, November" sounds like military phonetics, spelling out "TYN". But that's all.
Also, but this might just be my artistic mind, I think the videos might be important, more important than you think they are. Some things in there seem out of place. The main character for example. He's in this strange lab, he knows where everything is, he knows what drawers contain what and he knows about that babel research thing, but he doesn't wear a labcoat. Makes it seem a lot like he just shouldn't be there. Like he got in there after whatever happened instead of having been there from the start.
Then, the video you get from clicking the ring has a different soundtrack playing in the bus. In the youtube video it's muzak, in the original one it's a news announcment.
And if I'm not mistaken, nosebleeds occur when being exposed to radioactivity. Nothing new, just kind of showing that they thought about everything, which is why I don't think the videos are just something minor.
