Hi Samuel,

Good job too.
I made nearly the same code as you ;)
And still not the same look.

With a link given by BW, i found more infos about lightning :
Graphics3D [
 Sphere[],
 Lighting -> {
  {"Ambient", RGBColor [0.40, 0.20, 0.20] },
  {"Directional",RGBColor [0.00, 0.18, 0.50],ImageScaled [{2, 0, 2} ]},
  {"Directional",RGBColor [0.18, 0.50, 0.18],ImageScaled [{2, 2, 3} ]},
  {"Directional",RGBColor [0.50, 0.18, 0.00],ImageScaled [{0, 2, 2} ]},
  {"Directional",RGBColor [0.00, 0.00, 0.18],ImageScaled [{0, 0, 2} ]}
  }
]
I didn't really understand the ImageScaled[] syntax, but even with these
parameters, the rendering is different.
