		<description><![CDATA[Here is a 3d Julia fractal with a Mandelbrot pattern that I whipped up in POV Ray. I&#8217;ve done some 3d quaternions before, but I figured I&#8217;d try creating patterned ones and this is a starter piece.
 
And here is the starter piece on which I patterned this Mandelbrot from POV Ray&#8217;s documentation.

		<description><![CDATA[In topology, a Klein Bottle is a kind of non-orientable surface, first discovered by the German mathematician Felix Klein.

The usual immersion of this surface is given by the equation:

The famous &#8220;figure 8&#8221; immersion can be expressed in parametric equations as:

		<description><![CDATA[I recently wrote a very short article on Wikipedia on Costa&#8217;s Minimal Surface.
I have been meaning to add a few renders and discuss the detailed topology, but haven&#8217;t had the time yet. However, here is a cool render of the CMS for now. Click to view the larger version.

The homotopy between a Roman surface and a Boy surface can be given by the following equations [1]:

for u [-PI/2, PI/2] and v [0, PI] and alpha varies from 0 (Roman surface) through 1 (Boy surface).
