Optical Illusions
I found this site quite some time ago:
http://www.ritsumei.ac.jp/~akitaoka/index-e.html
It came to mind when a graphic embedded in a problem "Three Different Trails" was being discussed by the Journeymen.
I am fairly sure that the illusion of gray flashing dots at the intersections within that puzzle is also on the above site.
Some of the illusions are quite different while some are variations of the first; ie they have a common theme. |

Re: Optical Illusions
One of the most well known optical illusions is that one where you can't tell whenether it's a vase or 2 faces. |
