Author description: One bug seems to flash on the left and the other on the right—although they’re really aligned one below the other, as you can see when the frame is removed. What’s more, a bug moving up and down looks like it’s going around an oval track, and two bugs flashing in the exact same place look like they’re separated. Instead of seeing objects at their absolute positions, we perceive where they are in relation to other visual landmarks, more so than is often recognized. This could make vision stable when the eyes move.
