Optical Illusion Sites

Optical Illusions & Visual Phenomena - an amazing illusion site put together by Michael Bach with explanations and interactive displays.  

 

Visual Illusion of the Month- Amos Storkey's excellent page of unique illusions. He says, "The aim of this page is to provide visual and optical illusions which I think are not the sort that are seen in 101 books etc on illusions."  

 

Illusions Gallery - Here is Dr. David Landrigan's gallery of optical illusions. Dr. Landrigan is a Professor at the University of Massachusetts Lowell in their Psychology Department.  

 

Archimedes' Laboratory - The visual illusions featured on this page are created by Gianni A. Sarcone and Marie-Jo Waeber. The illusions that the authors offer are, for the greater part, products of their own imagination, sometimes discovered by chance and in other cases they deliberately set out to discover new ways to view existing optical illusions and present them under a new light.  

 

Akiyoshi's Illusions - This site and the majority of optical illusions presented are the creation of Professor Akiyoshi Kitaoka, Department of Psychology, Ritsumeikan University, Kyoto, Japan.  

 

Eyetricks - Optical illusions, 3D stereograms and anaglyphs, fractals and brain teasers.  

 

Skytopia - An intriguing selection of old, new and exclusive optical illusions. Many pictures are enhanced via the use of 3D and animation.  

 

Project Lite is a software, curriculum and materials development project located in the Science and Mathematics Education Center at Boston University.  

 

Grand Illusions was originally designed as a way of sharing our enthusiasm for various science based phenomena, fun and games, and optical illusions. 

 

 Impossible World - A site devoted exclusively to the study of impossible figures. After gathering a big collection of impossible figures I decided to create a unique website about impossible figures where as much as possible information about impossible figures and impossible art will be published. 

 

NIEHS Optical Illusions - A set of optical illusions presented by the National Institute of Environmental Health Sciences.  

 

Perceptual Science Group - the Perceptual Science Group of the MIT Department of Brain and Cognitive Sciences at MIT does research in human visual perception, machine vision, and image processing.  

 

Museum of Unworkable Devices - This museum is a celebration of fascinating devices that don't work. It houses diverse examples of the perverse genius of inventors who refused to let their thinking be intimidated by the laws of nature, remaining optimistic in the face of repeated failures.
