But to test the explanation I tried covering  each image in turn and the effect was still there! I wondered if there  was a perceptual delay effect in that our memory of one picture affects  our interpretation of the other but then I also noticed that the effect  changes depending on where the picture is in our field of view. If I  position myself facing the right hand edge of the monitor, then the  right hand tower seems more vertical and the left one almost seems to  lean left or backwards. So the illusion may be more (or at least partly)  due to the fact that in the absense of other visual cues in the picture  we tend to interpret as if viewed from the direction at which we are  looking at the picture &#8211; ie we interpret the picture edge as a window frame.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>My friend Gerry Pareja forwarded a link to this story from &#8216;Improbable Research&#8217; about the first prize winner in the Neural Correlate Society&#8217;s 2007 Illusion of the Year contest.
