And I was just about to start something like this...I was actually a 
matter of minutes away from beginning coding on the first scene file. 
Thanks for saving me the work. :-)

Could you explain more about what you mean by "profile planks"?

The object pattern is not currently useable in isosurfaces, since it is 
a block pattern. This means it has an infinite gradient, and isn't very 
friendly to the isosurface solving method. I may attempt some kind of 
blur function for pigments, this might make it useable. An improved 
proximity pattern could also be useful.
