I still haven't done a test of using the proximity pattern in an 
isosurface, I am a bit afraid of how slow it might be.
One thing, media doesn't require as many proximity samples as an 
ordinary texture, since things get smoothed out along the media samples. 
An isosurface would probably need it as smooth(many samples) as possible 
for the solver to make any sense of things.

And your trace() + mesh technique certainly has possibilities...don't 
give up on it yet. :-)
