  • At the start of the video, the window was oscillating for me. In the middle of you showing the more circular illusion, I started seeing that one as rotating, then the next time you showed the window, I saw it rotating. I'm curious as to how it appeared as oscillating to me before, and yet now my mind broke the illusion.

    Chris CChris C11 soat oldin
  • If you really want to break through the illusion, just focus on the flat planes of the corners. They are the key to breaking it. As now, you can differentiate the sides and see the object spinning.

  • well, count me in amongst the "some" ...once I seen the shading as he was getting into I already knew that I won't be impressed by any of this. Instead of calling this illusion they should call it a "brain function gap" , human brains have plenty of those

  • i can force myself to see it but there is a half second where it looks like its stopping and going back where i lose it and repick it back up. really the only thing that lets me see it, is because the side waves slightly as it turns. if it was solid i'd never be able to keep track of it

  • I love this. I can see it correctly if I concentrate with the ruler in place as a guide, but my brain really wants to see the illusion. With the life-size window and you in it, I see it as rotating most of the time. Probably all of reality is twisted like this on a fundamental level and we are all fooled every day.

  • Just like you ball earthers. You clearly prefer the “illusions” of outer space, impossible speeds of earth, sun and galaxy and impossible evolutionary “theories” including ridiculous time frames over the truth! We live on a flat a stationary earth, space is fake and we ARE the center of the universe as it all rotates around us like the true time piece it PROVES to be year after year

    GARYtheFLATHEADGARYtheFLATHEAD16 soat oldin
  • If you recognise the qualities of the object before he starts rotating, you see right through it quite easily. In fact, I had to re-watch it to see the illusion, because at first I didn't know what he meant when he said "the window is rotating through me"; I just didn't see it. Interesting trick. I enjoyed it

  • Ok, I hereby Illegalize (is that even a word?) the ames window, it shall be considered dark magic that should not exist because my brain does not like how it tricks me.

  • Speaking of vision and how we perceive things, this might be a neat video also, why does my vision during the night become grainy looking where it is not during the day? And is there a way to fix this?

  • 9:54 bad example its intuitive that the face on the right sticks out because it appears larger and closer and it also has better lighting geometry, now if you made something duller that didn't shine as much and used a lighter pigment for the sunk in face and manipulated the scale slightly you could make the faces almost match or even give off the impression that the sunk in face is the sticking out face.

  • I loved this, we only perceive things in the way we are capable of, we need science to develop machines that can do this for us, physicist say there are more than 3 dimensions but we just are not able to see them.

  • The longer the video went on, the easier it was to ignore the illusion and actually see what was going on. Although, the example of the two faces where one was protruding out and the other was going inwards, I instinctively knew which one was which, so it confused me when it was said you could only tell when the image moved.

  • the saddening part is i stopped seeing the illusion halfway through the video, went back, and realized my brain's gone in it's "can't unsee" phase now once i figure an illusion out it doesn't trick me, idk why

  • The Ames room doesn't appear to actually be an illusion on our computer screens - because if you measure the images of the two figures, they're truly smaller when at the entrance than when to the left. In real life, it would be an illusion, but not on our screens.
