caption: A physical motion of a camera at a constant shutter speed may create temporal aliasing known as the wagon wheel effect. The velocity of the camera, moving towards the right, constantly increases at the same rate . Halfway through the 24-second loop, the objects appear to suddenly shift and head in the reverse direction, towards the right.
