Tick by Akiyoshi Kitaoka

This is an interesting motion illusion that Professor Akiyoshi Kitaoka created back in 2010.  When you simply look at it, you’ll just notice a series of different-colored square outlines.  But if you use your scroll bar and move the image up and down, something interesting happens.  As the actual image moves, the square insert also […]

Illusory Blue Dots by Akiyoshi Kitaoka

In this variant of the Hermann grid illusion created by Professor Akiyoshi Kitaoka, illusory blue dots can be seen in the white circles where the squares intersect.  This phenomenon was first reported in 1870 by Germany physiologist Ludimar Hermann.  The blue dots cannot be seen if you look directly at one of the white circles.  […]

Rotating Chains by Akiyoshi Kitaoka

The blue and yellow circles made up of what look like bicycle chains appear to spontaneously rotate.  Try focusing your attention on only one of the six circles at a time and you should find that the one you are focusing on stops moving.  If you want to maximize the motion effect, move your eyes […]

Another good example of this […]

Swimming Rings by Akiyoshi Kitaoka

Concentric Circles by Akiyoshi Kitaoka

Have a look at today’s image that was created by Professor Akiyoshi Kitaoka from Ritsumeikan University in Kyoto, Japan.  We’ve posted images similar to this one in the past, but I thought that it was a pretty good representation of an old optical illusion concept.  Each of the rings are circles, even though they certainly […]
