    Which way does the motion go? Is it up and down, or right and left? The truth is, the motion is entirely in your mind! In this demonstration, you first see a random texture moving up and down for 5 frames. After those priming frames, the remaining frames are completely random, but you will continue seeing up and down motion for several more frames. To convince yourself that this is all in your mind, try thinking to yourself "right left right left". The same sequence of random textures will appear to move whichever way your mind decides.

    "purely random" is wrong: Everytime I watch the video, I see the same clips

      It's meant to imply that it's using a different seed for the noise.

    Didn't work at all for me. I caught myself looking for a recognizable shape to follow and losing it in the random frames, so that may be why.

      @transcendentape It works better if you focus on the global motion, rather than on particular features.
