Ambiguous Arrow Illusion
Welcome everyone!
The ambiguous arrow is an illusion based on anamorphosis and forced perspective, which exploits the brain’s predisposition for finding right angles even though they are absent.
The video shows an arrow, pointing left, which is rotated in both directions. This object has three features:
- It resembles an arrow from a certain angle;
- The illusory arrow seems to never change direction;
- Its mirror image always points in the opposite direction.
This optical illusion, originally invented by mathematics professor Kokichi Sugihara, is a combination of mathematics, reflection, symmetry and viewing angle.
Reasons why...
- It is a conversation starter;
- Everyone loves and falls for illusions;
- It is a charming way of introducing adults to LEGO (art);
- It raises curiosity on how illusions can be generated, especially with LEGO.
