Hi(gh)!

After deciding to discard the smooth color gradients in favour of sharp 
stripes (which would be more true to the Amiga original), I now fixed my 
problem with the background texture (see attachment).

I now will apply this layered texture to six planes defining the cubic 
space in which the game level is located; they will be animated 
according to the player's (a simple ball) movements, just like in the 
original game!

Here is the code:

   diffuse 0

P. S. Yes, POV-Ray hurts when not exercised on a daily basis!
