ok, I get your point. That is caused by the way openGL rendering code is
written; somehow boxes have glossy surface and facets don't. I am in no
way familiar with opengl, it is mostly code Olivier has written in the
prehistoric (= pre-python) period. If you know something about opengl,
go for it, if you don't or don't have time, you can file bug about that.

Once I was trying to make specular light used, but then I gave up. The
chameleon highlight is made by changing periodically the ambient light,
the color of bodies doesn't have to be changed that way.
