    I really liked the editing in this video. You managed to effectively point out key features of some illusions using only visual elements.

    with the first illusion, i think it's also that the vertical line is on top of horizontal line, so it appears to our brain as though the width of the horizontal line contributes to the height of the vertical line

    • @ToyInsanity
      @ToyInsanity 8 місяців тому

      The vertical line is longer because it has a fraction of the horizontal line added to it.

      thats because in this pic they are squares not lines, now take a thin pencil and draw the same thing, look away a minute then look back, you'll see the same illusion, his explanation is correct, our eyes is configured to see more horizontal then vertical because of the adaptation of what we see constantly on earth, everything goes more horizotal

    I've experienced the motion aftereffect illusion after an extended period of time playing guitar hero - there are buttons moving towards you constantly on a moving fretboard and after a long time playing the game if you look away, e.g. at a wall or another part of the room, you see everything moving away from you.

    You should also talk about the optic nerve blind spot! Also, this is super interesting for me. I am almost completely blind in my left eye so my vision is 2D. None of the 3D illusions work for me at all

    • @David.C.Velasquez
      @David.C.Velasquez 9 місяців тому +5

      Your brain's visual processing centers, actively hide the 'blind spot' from your consciousness. Can you imagine if this wasn't the case? You would be aware of a 'hole' in your visual field, that would likely breaking any illusion of immersion.

    • @nfrcomputers
      @nfrcomputers 9 місяців тому

      @@David.C.Velasquez yes, but look up optic nerve blind spot and read the wiki article. you can prove that it is a real phenomenon by the test on wikipedia or on another website. you close one eye and look at a dot in the center and a off-set dot. at a certain specific eye distance the off-set dot seems to dissapear into the background when the eye is focused on the center dot.

I saw you don't make videos often and it's my (selfish) hope you'll be able to them more frequently. Thanks for what you do.

    14:50 this was created in real life. It's an installation in a little walking path along a little river in Freiburg or Straussburg. There are three bars, the left goes diagonal pointing up and away from the viwer, one longer horizontal, the right also diagonal pointing up and towards the viewer \_/ some 20 or 30 feet away , a couple feet off of the ground was a plate with a small hole. Crouched and looking there only there, you see the impossible triangle.
    I'm sure others have done it, but thank you for talking me back to that
