On a slightly different note - why is there a guy rolling a ball down the grooves in the floor ? http://www.optical-illusionist.com/illusions/public-lavatory-false-wall/ Fri, 15 Jan 2010 07:27:42 -0600 These two images of the Leaning Tower of Pisa are identical but if you look at them closely you'll notice that the tower on the right appears to be leaning more than the one on the left even though there is no difference between the two.

To those in the west who are used to being indoors this picture can appear to show a family sitting in the corner of a room with a window through which vegetation can be seen outside. Show the same image to someone in Africa however and the perception changes, the rectangular room corner looks like a tree and the window appears as an object being balanced on the woman's head. http://www.optical-illusionist.com/illusions/cultural-optical-illusion/ Mon, 12 Oct 2009 10:56:40 -0500 Another double meaning illusion, does this picture show a plate with a fish on it or does it show a girl's face ? http://www.optical-illusionist.com/illusions/fish-or-girl/ Sun, 04 Oct 2009 09:36:42 -0500 A classic double meaning illusion, is this a drawing of a man with a moustache or is it a mermaid at the bottom of the ocean ? http://www.optical-illusionist.com/illusions/man-or-a-mermaid/ Wed, 30 Sep 2009 08:07:53 -0500
