Summary
[edit]DescriptionH αντιληπτική πλάνη του πλέγματος Hermann σε επένδυση τοίχου με πλακάκια.jpg |
English: It is an optical illusion . The brain sees grey blobs at the intersections of a white (or light-colored) grid on a black background. The grey blobs disappear when looking directly at an intersection. The same happens here. The photo was taken from a toillete wall. The material you see is tile as wall panelling. As you can see with the green colour you have the same effect. English: Grid illusion on a wall tile |
