Before you start reading this, count the circles in the image below. How many are there (if there are any)? Also known as Coffer Illusion, this optical illusion was created by Anthony Norcia and qualified for top 10 category in “Best Visual Illusion Of The Year Contest”. Anthony describes this visual phenomennon like this:
First time viewers of this display invariably do not see the 16 circles segmented from the background. Rather, they see a series of rectangles that they frequently describe as “door panels”. The illusion pits segmentation cues against what appears to be a very strong prior to interpret the image as a series of 3-D structures “coffers” with closed boundaries. (A coffer is a decorative sunken panel.) It appears that the prior involves both closure and shape-from shading assumptions.

cool…i see 16!!!
I didn’t see that at first but now I do, it is sooooo cool. I don’t see how anybody could see 25

if u say 25 i think that u r rite but those who say 16 thins is how we got 25… u hav just counted the small circles but if u imagine this as the little circles u will c wat i meen

am i rite?
I See 25
i ddint get it at first bubt you look at the x and thres lke 15 or 16 but im pretty sure 15
Yes there are 25 that I can see. There are straight lines in a circle, you can use a protractor, measure each 10*(degrees) around the circumference and draw 180* diameters conecting all the 10* around the circle. That is how you can see circles in the corners of the coffers If ther are two coffers next to each other either vertically or horizontally.
16
this illusion is posted wrong
your supposed to stare at the white cross and then 16 circles start to appear and eventually that all you can see
people seeing more either cant count or are seeing circle fragments and imagining more because thats what they wantwbxvkd
i see 16 baby
..i found 32.
16!!!!!!!
Is the illusion that the circles are there or that they are not there?
THere’s sixteen!oh yeah!
Staring at the X helps. Wow…that’s cool!!!
The people that see 25 are seeing the parts between the “real” circles. What you are supposed to see is that the vertical lines all make up the background and the horizontal lines are all in the circles. So if you see horizontal lines, they are part of the 16 circles, and the vertical lines are all part of the background. Basically, the people who see 26 are looking at the spaces between 4 of the “real” 16 circles and thinking they kinda look like circles, too.
There are really twenty-five circles
AT FIRST I THOUGHT THERE WERE ONLY 16 BUT THEN I LOOKED REALLY CLOSLY AND SAW 25 AND THEY ARE NOT FRAGMENTS OF A CIRCLE
Wow, it all depends if your eyes try to line them up straight or sideways. fantastic.
Huh wtf how can you see 25 circles??? there are only 16…
i see 25!
I see dead people
i only see 16. i can’t find 20 or 25.
lessa is right we found 25 circles
audit i can’t find any how do u do this
Topperrrr! >> 31
Or:
Hmm, there are no circles. There are only approximations (..duh..) of circles; 16 of them are 'clearly' visible between the groups of vertical lines; 9 more are suggested (and incomplete at the bottom and top)in the complementary space between the circles mentioned first; and the final 6 are in the same vertical space but then cut off by the boundaries of the picture.
Wow… that was like magic! After like 10 seconds they magical appeared =)
I saw them before
9+16
i was gonna say 16 but it’s 25 :)
I see
