So noted!  He did an excellent job, especially that clever bit about employing
f_r - which took me a bit of time to wrap my head around.

f_r(x,y,z) = sqrt( x*x + y*y + z*z )
When used alone, the "R" function gives a surface that consists of all the
points that are a specific distance (threshold value) from the origin, i.e. a

Indeed.  I think he could get some interesting half-tone effects as well.

rgbf would look great if unmodified spheres of all 3 colors were used.

There's also the potential for using different shapes - boxes, triangles,
hexagons, etc.  I'm also thinking that using cones would give a Voronoi effect.
