We see a completely new mode for the Eye in the Dark Dimension. With a flourish of his right hand over his left forearm, a band of green lines begin orbiting his forearm just below his wrist. (Another orbits just below his elbow, just off-camera in the animated gif.) The band signals that Strange has set this point in time as a “save point,” like in a video game. From that point forward, when he dies, time resets and he is returned here, alive and well, though he and anyone else in the loop is aware that it happened.
In the scene he’s confronting a hostile god-like creature on its own mystical turf, so he dies a lot.
An interesting moment happens when Strange is hopping from the blue-ringed planetoid to the one close to the giant Dormammu face. He glances down at his wrist, making sure that his savepoint was set. It’s a nice tell, letting us know that Strange is a nervous about facing the giant, Galactus-sized primordial evil that is Dormammu. This nervousness ties right into the analysis of this display. If we changed the design, we could put him more at ease when using this life-critical interface.
The initiating gesture doesn’t read as “set a savepoint.” This doesn’t show itself as a problem in this scene, but if the gesture did have some sort of semantic meaning, it would make it easier for Strange to recall and perform correctly. Maybe if his wrist twist transitioned from moving splayed fingers to his pointing with his index finger to his wrist…ok, that’s a little too on the nose, so maybe…toward the ground, it would help symbolize the here & now that is the savepoint. It would be easier for Strange to recall and feel assured that he’d done the right thing.
I have questions about the extents of the time loop effect. Is it the whole Dark Dimension? Is it also Earth? Is it the Universe? Is it just a sphere, like the other modes of the Eye? How does he set these? There’s not enough information in the movie to backworld this, but unless the answer is “it affects everything” there seems to be some variables missing in the initiating gesture.
But where the initiating gesture doesn’t appear to be a problem in the scene, the wrist-glance indicates that the display is. Note that, other than being on the left forearm instead of the right, the bands look identical to the ones in the Tibet and Hong Kong modes. (Compare the Tibet screenshot below.) If Strange is relying on the display to ensure that his savepoint was set, having it look identical is not as helpful as it would be if the visual was unique. “Wait,” he might think, “Am I in the right mode, here?”
In a redesign, I would select an animated display that was not a loop, but an indication that time was passing. It can’t be as literal as a clock of course. But something that used animation to suggest time was progressing linearly from a point. Maybe something like the binary clock from Mission to Mars (see below), rendered in the graphic language of the Eye. Maybe make it base-3 to seem not so technological.
Seeing a display that is still, on invocation—that becomes animated upon initialization—would mean that all he has to do is glance to confirm the unique display is in motion. “Yes, it’s working. I’m in the Groundhog Day mode, and the savepoint is set.”
