After Loki has enthralled Selvig, enthralled-Hawkeye lets Loki know that, “This place is about to blow and drop a hundred feet of rock on us.” Selvig looks to the following screen and confirms, “He’s right. The portal is collapsing in on itself.”

This is perhaps one of the most throwaway screens in the film, given the low-rez twisty graphics that could be out of Lawnmower Man, its only-vague-resemblance to the portal itself…

c.f.

…the text box of wildly scrolling and impossible to read pink code with what looks like a layer of white code hastily slapped over it, and—notably—no trendline of data that would help Selvig quickly identify this Very Important Fact. Maybe he’s such a portal whisperer that he can just see it, but why show the screens rather than show him looking up to the blue thing itself?

There might be some other data on the left of this bank of screens seen a few seconds later in the background…

…but it has more red text overlays, so I’m disinclined to give it the blurry benefit of the doubt.

Fair enough, this is there merely to establish Selvig’s enthrallment, and the scientific certainty of the stakes for the next beat. But, we see his eyes, and the certainty is evidenced by everything collapsing. We don’t need scientific assurance. If the designers were not given time to make it passable, I wish that the beat had been handled without a view of the screens rather than shaky-cam.
