Ok, thanks. I'll have to investigate lighting in this commit  then...
I know a few things about GL lighting concepts, but yeah : the strip 
code looks like magic!
Note that the problem is independant on strips : the same bug appears 
with GLlisted glutSpheres.

using glLists for spheres result in overlighting

Bug description:
I just fixed the "strip" code for spheres, but there is still a problem with "over-lighted" spheres (see attached image). Probably only a problem of tunning gl parameters. The same thing appear when no-strips spheres are displayed using glLists.
