No, you have not had one beer too many. These images of the Leaning Tower are actually identical, but the tower on the right looks more lopsided because the human visual system treats the two images as one scene. Our brains have learned that two tall objects in our view will usually rise at the same angle but converge toward the top—think of standing at the base of neighboring skyscrapers. Because these towers are parallel, they do not converge, so the visual system thinks they must be rising at different angles, as demonstrated by this year’s winner of the Best Visual Illusion of the Year Contest, sponsored by the Neural Correlate Society.
Just to test it out I copied the picture on the left and pasted it twice below.
Now that’s interesting.
Update
Someone (high) wondered what 3 copies would look like.
Now that’s really interesting.
Are you positive you didn’t copy the one on the right?
kewl
Just another view outside of Jonco’s window.
I’m under the influence of high test beer and some BC bud. They look the same to me.
Could someone (Jonco?) get 3 of them together?
Would the left and right ones converge to the center?
How about a “montage”? 3×3, 4×4?
Hurry, I’ve only got a couple buds left.
interesting – the sky also changes color on each one!
Let’s try 25 copies – maybe the last one will be horizontal!
