		<description>I thought at first it was an in-joke. Then I started to think, &quot;no I think they actually believe this.&quot; There then followed a mind spinning few moments where I wasn&#039;t sure if I was part of a joke or peer pressure was creating a reality. Either way I thought ... &quot;stuff it&quot; ... so I barged in. Yeah, totally shameless.</description>

		<description>Actually, the real version of the chessboard illusion is my all time favorite.  I have cut out a square and moved it back and forth, and dang if it doesn&#039;t match them both.

The board on this site is broken though.</description>

		<description>I think the site should be called Optical Illusion Illusions.

At first I thought the Checkerbox illusion was discordant because: here was a &lt;i&gt;real&lt;/i&gt; illusion. No, however.  If you color-sample it, he&#039;s doctored it so they actually are different shades (!)</description>

		<description>Hmm. Is this a gullibility test? Because there&#039;s nothing wrong with many of the things shown. The cube is just a regular box shape. The stairs are not paradoxical. Nah. These are not as advertised. Clever trick though.</description>

		<description>It is very cool how the &quot;devil&#039;s tuning fork&quot; at first looks like it has 2 prongs but when you look at it really closely and cross your eyes just so, you see it actually only has two prongs.

It is amazing how the mind works, just making them round cylinders at one end and rectangular bars at the other tricks your mind into believing that there really are two prongs when in fact it has at least, no more than two.</description>
