Here is an other povray scene from
Jaime Vives Piqueres
from 2004. Also this scene has made Jaime Vives one of the leading Povray artists in the world.
Unlike the
gears example there are no textures used here.
It uses sophisticated lighting macros (also written by
Jaime Vives Piqueres in 2003) using an Emissive Spectral Data Library (by Jaime Vives too).
