Out of all, I only saw it rotate once. Other times, it works
dBap_Lp-0oc&t=9m59s 9:59 it's obvious it's the one on the right since it casts a shadow.
dBap_Lp-0oc&t=1m52s 1:52 try visual meditation. close your eyes and take a visual inventory of everything in your home or around you. Then close your eyes and visualize everything until your mind starts to get blank/fuzzy. I can force myself to see this image both ways.
Ouchie ow my brain
i dont see the ilusion
If you are looking to get rid of that giant Ames Window let me know :) I have a great use!
I don't see it oscillating.. Is that abnormal?
I first saw the Ames window and the room illusion in the 1950's in a Moody Sermons from Science movie.
Trippy
I see the Ame’s window spinning, stopping, and keep’s going in the same direction.
This is the reason we still could not imagine a 4 dimensional object, our depth perception of the world are just guesses, our perception is 2 dimensional. We are seeing a 2 dimensional projection of a 3 dimensional world.
So it is not an optical ilusion but it have to be called ,,the brain failure''. 🙂
Fake video. When he is hanging on the door you can obviously see that it’s spinning and then when it’s behind a black screen it dosnt. Obviously just video effects. I don’t believe you one bit.
Omg... the nerd dad joke 🤣
for some reason I can see it's true rotation when it's alot smaller.
if u shake your phone and let your eyes settle so it’s all a bit blurry it becomes a lot easier to perceive what’s happening.
dBap_Lp-0oc&t=9m51s 9:51 Not true! You can use the shadiw que to figure out which protrudes and which is the impression.
me who can solve a rubik’d cube in 20 seconds:
