Playing with an idea.

The attached image uses multiple isosurfaces as colored dust. I used 
yuqk's new f_popnrm_rnoise() to break shapes up rather than my usual 
method with extreme turbulence blowing isosurfaces apart.

It kinda of works as far as I've gotten...

The thought - still untested - is given these particles exist, it should 
be I can project light from the backside 'through' them and into 
scattering media between the camera and the particles.

The effect counts on fairly heavy AA (it's effectively part of the 
sampling / color-blending). With media too - this method might get 
really slow, but we'll see.

Off to do some RL stuff, but I'll try and get back and try the projected 
light / media part of it soon.
