IMAGE DESCRIPTION: 
    The idea of the scene comes from a picture made
by Escher which is called 'another word'.
 1st topic : Gravity. There are three different axis of gravity in
   the same scene.
 2nd topic : Hilbert curve. There is an Hilbert curve which is hung
   between the two colums. This curve is interesting because it is
   a curve which fills a surface. And its particularity comes from
   an amazing property : if you draw a vertical line exactly in the
   middle of the Hilbert curve, your line will cut only one segment
   of the curve; if you make the same with an horizontal line in
   the middle of the curve, your line will cut two segments of the
   Hilbert curve; if you draw a vertical line at the 1/4 or at the
   3/4 of the curve, your line will cut three segments; and so
   on ... 
 3rd topic : the node situated at the left of the man.
 4th topic : the moebius which has only one side.

DESCRIPTION OF HOW THIS IMAGE WAS CREATED: 
    The Hilbert curve was
generated by a genetical algorithm within the pov script. The biggest
problem encountered was to avoid the usage of arrays which are not
available in POV 3, that's why I used the include mecanism. For
each new day of generation of the fractal, I need a new included
file, that's why there are as many files as the depth of the curve.
All this technic is available in the POV script situated in the Zip
package. No additional tool was used.
