Elements that move in the same direction at the same time are perceived as belonging to the same group, even if they share no other visual property. The Law of Common Fate is one of the original Gestalt principles, and it is the one grouping cue that depends entirely on motion rather than static layout. A flock of birds reads as a single flock, not as hundreds of unrelated dots, purely because every bird shifts in the same direction at once.
