The Rotating-Tilted-Lines-Illusion

Gori, S. & Hamburger, K. (in press). Last but not Least: A new motion illusion - The Rotating-Tilted-Lines-Illusion. Perception.

This apparent motion illusion was created by Simone Gori (Italy) and Kai Hamburger (Germany) in January 2005.


While approaching the Rotating Tilted Line Illusion (Gori & Hamburger, in press), the radial lines appear to rotate in counter-clockwise direction,
whereas when receding from it, they appear to rotate clockwise.
It presumably represents the simplest form of apparent motion illusions where self-motion is required for perceiving circular rotation.

This illusion has first been published in: Martinez-Conde, S., Pérez, M. & Martinez, L. (2005). Flipar en Colores. Quo, July 2005, 110-115.


A more complex version of the previous illusion. In this version the illusory rotation is stronger and there may be some residual counter rotation in the surround.
