THERE are 16 circles hidden in this striped, 3D-like optical illusion.
It is extremely hard to focus on finding circles while you are staring at this barcode-like image.
“First time viewers of this display invariable do not see the 16 circles segmented from the background,” wrote illusion creator, in 2006.
“Rather, they see a series of rectangles that they frequently describe as ‘door panels,'" he explained.
They are also known as coffers which are sunken panels commonly found on ceiling.
Coffers are often in the shape of a square, rectangle, or octagon and decorate famous structures like the Pantheon in Rome, Italy.
“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,” wrote Norcia.

Norcia used both horizontal and vertical lines that easily blend into the background, making it difficult to spot all of the circles.
The lines are also different thicknesses and shades of grey making it challenging to focus.
