To use the pov utility as described in the article

to point to the povray installation directory.
E.g:
POVRAY=/usr/local/povray31g/povray31

afterwards you can use this pov script as follows:
./pov burbujas 6 9 1 5 1 5

The parameter passed to the script are:

     Source file is burbujas.pov 
     Size 6 = (400x300) 
     Quality 9 
     Intial photogram = 1 
     Final photogram = 5 
     Initial clock = 1 
     Final clock = 5 
pov requires that you have imagemagick installed. It need
the programs convert and animate from imagemagick.
