Here's a balls-on-plane image I used to fiddle with some blurred reflection
stuff, the aim being to give the balls some apparent weight, like ball
bearings or something rather than the common 'plasticky' mirror finish.
Still needs some work but looks OK I think.  The blurring is done with the
common small-normals trick, but I spent some time playing with the
reflective exponent to get the unusually stark reflections.

I'd say you acheived your goal. Nice.

Are you using a light probe, or just plain lighting?

Nah, it's just plain lighting.  I'm not experienced with light probes, which
would be something I guess I should get into.  It's just two lights: a key
area light with smallish volume quite high and right of the scene, and a
dim shadowless fill light to the far left.  The whole thing's in a big
white box which is where most of the reflected lighting comes from.
There's no radiosity or photons used in this test scene, though with such a
lot of low-exponent reflectance I doubt those effects would make a great
deal of difference.

Impressive.

Looks like I have many more things to learn.

Hope I'll be able one day to do this.

Very Nice!
any chance you could post the floor texture?

Sure thing, it's real simple - the only thing that makes it look good is the
reflections and lighting, so you might want to play around to get the
effect right in a different scene.  The exponent in the reflection block is
really the only thing different from a bog-standard reflecting plane.

plane {
  y,0
  texture {
    pigment {
      checker
      color rgb 1
      color rgb z*0.4
    }
    finish {
      specular 0.6
      roughness 0.01
      diffuse 0.5
      reflection {
        0.2,0.5
        exponent 0.75
      }
    }
    normal {
      granite 0.02
      scale 0.1
    }
  }
}

Incidentally, it's probably pretty obvious what I was thinking of modelling
when I posted four balls in a row!  So I've attached a render of the (very
little) work I've done on it so far.  Nothing fancy, but you can see the
metallic texture looking OK somewhat more in situ.
