Flemish is almost the same as Dutch, that's why most people refer to both
languages as Dutch. I don't really agree with this.  In my opinion, Dutch
resembles Flemish not much more than it resembles Afrikaans. (please, don't
start a discussion about it, I'm tired of those discussions...)

nog ne goeiendag!

I'll change that in the docs (12)

Ah! Is this intended?

My impression was wrongly formed by placing several randomly generated objects
next to each other. The different viewpoints was just enough to convince me that
there were minor differences.

Still, the original point remains, R2 = seed(rand(R1)) is still a waste of time.

  I would guess that the random number generator algorithm used in povray
uses just integers.
