I wonder if rendering something even remotely resembling this would be
possible with POV-Ray by using its 4D Julia object:

  Anyone feeling inspired?-)

Quite probable, as it realy looks like a julia fractal. You just need to find 
the right set of parameters.
High iteration count. Right 3D slice. Right 4D vector, algebra type, function 
type, distance...

  I'm not worrying about the parameters. I'm worrying about the texturing.

pigment pattern seems rather simple: either a plain pigment with a set of 
colored lights, or a 'wood' colors pattern along the longest axis, with a 
big scale ?
Dropping shape information, the coloring is rather green/red/yellow 
(which is a mix of green & red, so should really have only two basic 
tinctures)

Notice there is nearly no blue components... just a light green and a 
light red.

Except for the odd edge effects it's just solid metal color
with good lighting. (see image in p.b.i.)
