Usually I used my own blob  (AKA metaball) function:
    field=sum(d/(pow(x-a,2)+pow(y-b,2)+pow(z-c,2)+0.001))
 a,b,c are center coordinates and d is strength. And while playing with this formula I
discovered  funny thing: if we use power other than 2, for example, 4 or even 8, we
get blobs, shaped as 
rounded cubes, looking very similar to superellipsoids. I know, superellipsoids have a
little bit more complex formula, but this one's divider
(pow(x-a,2)+pow(y-b,2)+pow(z-c,2)) represents 
a particular case, when e=n=1 (look in POV documentation, superellipsoid article). 
 Image attached.
  If anybody interested in scene source, I can post it into p.b.s.-f.

 Sincerely Yours, Alex Kluchikov.

I would like the source please.  Not just for the shape but also
for the colors you used!
