New wallpaper.

Yeah, I'm in a rut. Was a material test to begin with, evolved into this.

Nice! Bright, hard, cold, well polished copper spheres with some condensation on them.
Like those RSOC.

Really nice ... but I didn't see condensation ... I see tiny chips and
dings...

  I see that too. The thing with copper is that it's 'very' soft and what I 
would call 'draggy', (that metal 'moves'!) For me, the main copper sphere 
had rolled down a tarmacced road for a little while, but having said this, 
the weight of that sphere would also produce surprisingly larger dents too.

I was thinking the same thing. Too hard. I've stripped enough copper 
wire to know that you couldn't make a ball bearing out of it. Makes 
great connecting rod bearings, however, but I'm getting off the point. 
Color and finish look convincing.

Hmm, I need to work on scale, I think.... Anyone ever have a BB gun when 
they were kids? This is sort of the inspiration... A close-up look at a 
copper BB. As I remember they tended to get a bit knurled at times. So 
yes -- not condensation, but dings (I think the normal was actually 
called "chinks" in the source file.)

A BB is rather small, and doesn't have very good mass, I need to add a 
bit of oxidation to the finish as well, I think.

Does copper really have such sharp reflections? Pennies sure don't.

I think most of the time, no, but then we have those examples of early 
Roman copper mirrors and so on.  It can be polished up. Just like brass. 
  We used to do this to the copper plates we used for etching.  We used 
brass cleaner.  It really creates a mirror-like and deeply luminous 
surface.  Slightest oil smudges from your fingers would stand out.  But 
surface dings would look less like pocks and more like gouges where you 
could see the metal displaced.  True pocks would fill in with grunge.

     The oxidisation might be a tough one. If it's that kind of surface 
you're looking for, then try a little green and grey in there too. Having 
said that, it doesn't ring true for this image:

     I suspect though, that this sphere is an old beaten sphere that's been 
lovingly handled through the years, and has kept a nice sheen. Still, it 
gives a better idea of what your surface should look like.

Maybe, but at first look, those specks made me think of tiny water droplets on the
balls surface.
