Another lambda picture - beautiful to look at, but still completely 
inappropriate for a logo. :-(

I'm trying to get that hyper-shiny look that all Apple Mac stuff has. 
But so far I'm nowhere near...

No, you're getting somewhere, as far as a useful logo goes. Just 
remember those Apple icons rely on sort of a subsurface scattering 
effect, like a translucent gemstone. Some scattering/absorption media in 
the circle would help with that. You would have to specify photon 
interaction with the media, of course. The finish would have to be 
reflective (with fresnel or falloff), and there would have to be a 
sharp, white reflective texture or surface in the sky somewhere.

Just remember that Apple's stuff is all hand-drawn vector graphics, not 
raytraced. There's probably quite a bit of artistic license in there.

(Unfortunately, I massively lack skill in that direction.)

Just a humble suggestion - Have you tried making the lambda symbol rounded,
to match the sphere? For example:

#local Symbol = text {ttf "C:\Windows\Fonts\Arial.ttf" "S" 1, 0}

#local RoundedSymbol = object {
   union {
      intersection {
         object {Symbol translate <-max_extent (Symbol).x / 2, -max_extent
(Symbol).y / 2, -1.001>}
         sphere {0, 1}
         sphere {0, .96 inverse} //Separate symbol from sphere slightly
         texture {T_Chrome_3D}
      } //intersection
      sphere {0, .94 texture {pigment {color White} finish {specular .4
roughness .006}}}
   } //union
} //object

object {RoundedSymbol rotate 30 * y}

That's true. The stuff looks like sss, if what I meant.

Hey, I'm sure if you try to copy a look and all it's attributes, you'll 
do just fine!

i think you should use splines for the lambda instead of straight cylinders.
not bad, otherwise.
