finish { ambient 0 }
finish { ambient 0 diffuse .3 reflection { .2 .4 } metallic .7 brilliance 
1.2 }

will need 2 macros to make any sens, or one macro to be used like :
Fin(0, -1,-1,-1,-1,-1,-1); 
where -1 means "default value"


ok, It was just a suggestion. Meany peoples says "what, I had to write 10 
pages to get a simpel image ? no - thanks" and it's not easy to convince 
them... well - theirs problem ;)
