Thanks for the comments and suggestions,

Iknow cylinders are a bad choice to create lots of hair but I've choosen 
cylinders just as a test if my script got the normals right and the 
number of placed objects to see the limits of my machine (P4@3GHz-1GB, 
you can imagine that even my swap of 1GB was nearly exhausted with X/KDE 
running). The color was just choosen by convinience and was intended to 
be different from the orignal mesh texture to see things better. Take it 
as very early WIP. But I was so amazed that it worked, that I posted it 
even if I know that right now the picture is far from beeing eye-pleasant.

The roadmap towards a final version is to write a macro to create a 
small patch of hairs (and I will for sure take a deep look into your 
Surcoat2Hair-Macro, if you allow) which then will be placed. Maybe I 
modify the PERL script and store also the uv's for the positions. This 
would make it possible to use an uv map and eval_pigment to fine tune 
normals at specific regions of the mesh, or just color adjust the hairs 
patches.

There is also a quite vivid thread how to only place objects where they 
are visible, which I follow with interest.

And if all works as had planned it, I will clean up the PERL sript 
enrich it with comments and make it aviable (probably in p.b.utilities).
