In this optical illusion, do you see one continuous line or a bunch or small pieces, not quite straight?


Scroll down for the answer and explanation.





Yes, they are... Really.


We try to convert a 2D image into a 3D one. We interpret the black lines as being drawn in perspective, sort of like a wall going off into the distance. The lines would have to be parallel to do that. Our mind then adjusts the lengths of the red lines, seeing the one as being closer and the other as being further away.
