ANIMATION DESCRIPTION: 

Two Rubik_s cubes compete in self-solution. 

DESCRIPTION OF HOW THIS ANIMATION WAS CREATED: 

This is my first animation, so I chose to keep it visually as simple as
possible. When it comes to modeling or texture, there is nothing special.
The turns are controlled by an array of 27 vectors, one for each small cube. The
vector tells the amount of rotation round the axes. I also used a status array
to keep track of which of the small cubes (numbered from 0 to 26) is in a given
location after x turns.
The splines of povray did not work as I expected, so I wrote my own.
To save time I chose not solve the Rubik's cube from scratch but use instead an
example presented by Lars Petrus on his webpage "Solving Rubik's cube for
speed" at http://lar5.com/cube/
Everything was done with PPP (paper, pencil and povray).
