Hi Karsteen.

Just in order to definitively close this argument (for me)....

@You : "...Sometimes I have the Feeling that some guys here are not amused that someone is writing nodes here..."

I sincerely hope that you are not referring to me, because, even if I always said that my mathematics knowledge is very weak,
I wrote some utility nodes too, nothing really special although :), and some commands/script and new others will come :).

I think too that your contribution to P. Elephant is excellent.

So I really love "developing" as much as "modelling" side!

I hope that I made myself clear this time.

Have a nice day.

Ciao!
