As every year, the NGO Neural Correlate Society (NCS) has held the contest for the best optical illusions of the year, in which researchers from all over the world present a video project where they put human nature to the test and demonstrate that not everything that is seen or heard is necessarily such and how we perceive it
The three winners of the 2022 edition demonstrate the ability of light, perspective and painting to alter perception and make us believe that the walls can be invisible or that the pictures can ‘come to life’.
One of the most emblematic scenes of the popular Harry Potter saga of novels and films is the entrance to the wizarding world. At London’s King’s Cross station, platform 9 ¾ has become a point of interest for fans of the wizarding world, the brick wall that Hogwarts students cross each year to start the course.
The contestant from the United Kingdom, Matt Pritchard, won the first prize of the edition taking inspiration from this iconic place, reconstructing it with LEGO pieces to show, through light, an optical effect through which a car can go through the brick wall Just like in the Harry Potter movies.
From the perspective proposed by the video, the vertical and horizontal bricks line up and seem to form a solid wall. The pattern camouflages the edges and makes it very difficult to distinguish the discontinuities.
The second prize corresponds to the American contestant John Salmon, who from the beginning tries to challenge the viewer with the name of his project: a tower of cubes?
What looks like two towers of symmetrical cubes, results in a striking visual deception. After inserting a stick through both towers, the investigator reveals that the cubes on the right are totally different ways what they seemed at first.
The ‘illusion of the hollow faces’ is the optical effect by which the American artist Wendy van Boxtel completes the podium of the 2022 edition. An effect by which the face of the woman painted on the canvas movesapparently, with the viewer, keeping the gaze from left to right and from top to bottom.
“I experimented with many materials, colors and depth, after many attempts I found a method that worked,” says Cornelia. In addition, she points out how the effect does not affect everyone equallysince those who suffer from schizophrenia cannot see the illusion because of the functioning of their brain.
