horizontal_motion _parallax.mp4

This video illustrates the horizontal motion parallax. It is the direction for the binocular vision. That is why you can see different points of view of a seen (here, two objects: a red moon and a blue star). Even if the binocular effect is not possible to reproduce with a simple video, you still can guess that the blue star is in front of the red moon (which is in a back plane) thanks to the horizontal motion parallax.
