A nickering light came from the corner of his vision.

Something dark flew by a corner of his vision and hit the floor.

But there was a message light blinking now at the corner of my vision.

From one corner of his vision, there was something else.

Something, someone, had slipped across the corner of his vision.

Something else was moving in the corner of her vision.

There was a tearing at the corners of his vision.

Someone moved at the corner of his vision, but nothing mattered.

One-Eye turned just enough to place him at the corner of his vision.

But all the landscape near the corners of his vision had now begun to move.
