Right you are, once again one character causes all the problem... Thanks!

That fixed code takes a bit longer to run, but all told this image took 
less than an hour, 800^3, n=8.0, radiosity, and the media halo uses the 
same df3 (you can see how the smooth scaling works). This isosurface was 
created by using function{0.06 - df3_func(x,y,z)}, the 0.06 part can 
then be tuned to make the surface 'grow'.

Now I wonder if it's worth doubling the integer size in the df3 to 
remove some of the grain.
