What you see below is another example of the Ebbinghaus illusion, also known as “same size” phenomenon. Although, in perspective the sphere in the right far end seems larger, in reality both spheres are exactly the same size. We saw exactly the same effect before with our funny nuns. Another example was little more scary – the same size monsters. I like all of them, how about you?

Wow! I can’t even tell that they are the say size now that I _know_ that! I need a ruler… :)
O.o how are they they same size? The one on the right touches the wall…and has a bigger shadow… unless the space between the walls is smaller at the back, but it doesn’t look like that either…
I thought an illusion was when it looks bigger but isn’t? It actually IS bigger.
FYI – the Mac Dashboard widget, at least for me, has not updated since the soulwax illusion – and the question mark came back – I had already downloaded the “fix” when the problem first came up….
Using the ruler function of the Web Developer Toolbar for Firefox, the front sphere seems to be 10 pixels smaller than the one at the back.
Hey vurdlak my mac widget does not work! I have downloaded the new version, but it just shows a little “?”, however the link still works.
Just thought i would let you know incase it has happened to anyone else
thats amazing…
That’s super cool. I think that this one is by far the best retive sizes ilusions.
… that is because they are not … a simple size test in photoshop clearly shows that the one behind has a larger size … its something like 5 pixels, but still … nice try tho …
try again…bottom 8 % smaller, by measurement.
They aren’t the same size. I just took it into photoshop and the sphere in the back is actually larger.
actually they aren’t the same size…I just measured them and the one in the back really is larger…:p
its lying. i measured.
they aren’t the same size… get a ruler and measure it yourself… the one in the back is atleast 1/8″ bigger…
mac widget doesnt work
the one that looks bigger IS bigger. i measured them.
how in the world are they the same size?!?! i just don’t see it lol.
I put a piece of paper on the screen and put marks on the edge of the paper to get the size of the front ball. Then checked it against the back ball. The back ball is BIGGER. Not by much but it is a little bigger.
catz
Well, that’s because they aren’t actually the same size. I just measured, the back sphere is slightly larger. However, it does still appear to be larger than it really is.
It still confuses me anyway. Good, but if anon. (comment 19)is telling the truth, it slighty runins the point. Good illusion though!
no 2nd pic?
This is stupid of cource there the same size but there saying if a person is standing pretty far away from you and you take your fingers and measure his size than hes an inch tall. its an extremely stupid illusion. it would work if they were the same depth
This is one of the best of this kind of illusion I have ever seen. It’s coo how your brain assumes that the walls are paralel.
How the hell are they different sizes!!! They are different!!!
wtf? they cant be the same!!!!! the one in the back touches the wall and the front touches!!!!! i dont get it. its cool but makes no sense….
I measured thrice, they’re not the same size!
ok you have to look at it like they’d be really close. one is somewhat lifting off the ground
anonymous, the reason they are the same size is probably cuz one end is closed in and the other isnt. and the angle they shot the pic at made them look diffrent sizes.
The rear ball is in fact larger, I mesured it
