Can you trust your eyes?


Optical illusions and visual perception from ESTER ALONSO

DRAGON ILLUSION



This is a wonderful optical illusion. This little dragon is made out of paper. You cut it out and stick it together, and stand it on a table. When you move around, the dragon´s head seems to follow you around the room. Have a look at the video to see what I mean.

How does it work?
If we move around when viewing a solid object, our brain knows how the object we are looking at should behave. However the dragon gives us the wrong clues, because we mis-interpret what its shape is. We assume that the nose of the dragon is pointing out towards us. but in fact the dragon´s head is concave.
If you want to try this illusion yourself, download the file and print it out. Notice that the instructions for folding and cutting out the dragon are included.
