		<description><![CDATA[  I&#8217;ve not been posting much because I&#8217;ve been struggling with a mammoth revision of my technical site on the Poggendorff illusion.  But now that&#8217;s done, here&#8217;s a post on another Poggendorff puzzle. In earlier posts I&#8217;ve shown examples of competition between illusions, and included a demo of a paradox when the Poggendorff and Muller-Lyer [...]]]></description>

		<description><![CDATA[This is a stereo picture-pair, but you can see what&#8217;s happening here without having to view the images in 3D if you prefer.  However,  if you&#8217;ve not got the knack, and would like to practice on this post, here&#8217;s how.  Hold up a pen about in the middle, between the two pictures, and about five [...]]]></description>

		<description><![CDATA[Does Big Ben look like it&#8217;s leaning over more in the right hand image than in the left hand one?  It can take a double-take to spot that the two pictures are identical. I find it a fantastically strong illusion. It&#8217;s a demo of a new illusion found by Frederick Kingdom and colleagues (you&#8217;ll need to scroll [...]]]></description>

		<description><![CDATA[There&#8217;s something amiss with this dagger, for sure. For a start, the blade&#8217;s a bit short. More important, you can&#8217;t be sure just from the picture where the blade is pointing. That&#8217;s because one and the same perspective view can arise from more than one three-dimensional configuration, out there in the world.  This dagger is [...]]]></description>

In the staircase lower left, where two of the long lines are either side of the outside edge of a step (in other words like lines a and b here, on the sides of a [...]]]></description>

		<description><![CDATA[One of the most obstinately puzzling illusions is Poggendorff&#8217;s, in which a slanting line interrupted by a gap no longer looks aligned. For over a century specialists have been unable even to agree whether it arises from 2D properties of the image, or as a result of attempts by the brain to interpret the configuration [...]]]></description>

		<description><![CDATA[Size constancy is the term for our tendency to see distant objects as larger than they are. So the far end of a shape with parallel sides looks wider than the near end. (See the earlier post on The Wonky Window). It seems to be such a basic feature of vision that it can give [...]]]></description>

		<description><![CDATA[Size-constancy effects make distant objects, especially in pictures, look larger. So in the table above, the back edge looks wider than the front edge. In fact, the sides of the table are strictly parallel. The fact that they don’t get closer together with distance, as we expect them to following the rules of perspective, produces [...]]]></description>
