I like your works, Thomas.

Would that macro generate each time the same kind of stone, or do you have 
some random generators which ensure that the output can be different each 
time (by user-selecting a seed for the random generator)? In any way, you 
combine observations in nature with your works in the POV-Ray SDL, and that 
is a tendency I like very much! Go on, Thomas, do much more of this!
