Unstable Fins
Optical-Illusion
An optical illusion is a visually perceived image that is deceptive or misleading.Optical-Illusion
Are the points marked with A and B in front, or in back? There are no depth cues, so its impossible to tell. As a result, the image becomes unstable and may appear to flip from front to back as you continue to look at it.

They always appear front to me, i guess i'm weired

it's kind of confusing
I had to look hard to get it to the front, once I did it flipped easy.
Wow that was awesome, it took me a while to see them in the back, but it was awesome!
'Twas fun...very fun...
i think that it's pretty obvious that they r in the back
At first I had no clue what you were talking about. Then I read it again and looked at the picture and literally jumped out of my seat!!
I agree, I didn't see it at first. Very good. I enjoyed the challenge.

Ive seen about 10 different versions of this

I thought A and B where in front but it was hard to tell because it makes my eyes hurt
Nice one! It took me awhile to see it. I kept thinking of them as two different shapes, and in 2 dimentions at first.

im with u rose
okay.....i am like =O!!Lol u do a lot of posting dont u....lol
this is so confusing. we definately need more of these. get our minds going.
it looks to me like it depends on which side you start looking at first is where the A and B will appear.Focus on where the 5 lines intersect on left and they appear in back. Focus on the 5 lines on the right and they appear in front. But for me if i focus on the right first it is hard to adjust when i focus on the left. Could be just me though
A looks like it's in front
Same with Freezinjoe. Kinda looks like they intersect... also makes your brain hurt a bit...
i dont think this one was very tricky... 'a' and 'b' are both in the back. it says there are no depth clues, however there really is. if 'a' and 'b' were in front, then how does it make sense for the back two fins to be larger than the front? depth perceptions tell us the further away an object is, the smaller it will be. based on that assupmtion, then clearly 'a' and 'b' both are on the back fins.
Go to opticalillusion.com and see 1,000,000 of these!!!!!!!!!
I never saw that one... GOOD ONE
Both are on the back.
Whooaaa... I could stare at that all day...
A and B could be in the front because they could just be smaller than the back fins. There's no rule saying that isn't possible. (If you're thinking it wouldn't balance, maybe it's hanging by a string.)
I look at these a lot and now I can switch which fins are in front at will... Great optical illusions!

Ack! >.< Makes me feel jittery when those fins flip sides.. kinda eerie. Thanks for posting!
It took a moment, but I finally got it to flip. Pretty cool.
wow...made me dizzy!
my favorite so far though!
my favorite so far though!
hmm, kinda like the one with the missing slice of cake, I can flip that one too
That is soo cooool.
A is in front, B is behind... that's how I saw it
Good one!
Nice, it takes a while for me to flip back and forth with whats in front then back!
ahhhhh my eyes
How do you see them as front?
I see them in the back.

Since the AB fins are smaller than the oter ones, I see them in the back cause of perspectives.
dont see them in the front only in the back
May 12, 2011
this iz soo easy all it is is a cuts through b
at first they were both in back later i saw them in front and after that i saw one in front and one in back. This is cool nice illusion.
that looks like a 3d x from the side and it made my eyes hurt
Coolness
Took me a sec
It's not that there are no depth cues; it's just that there are contradictory depth cues.
It's pretty fun to try and quickly switch between the two perspectives
Fun! I like it.
