Lighting is hard

Well,

I'm having a hard time with lighting. I'm developing a clsLight to deal with basic issues, but for some unknown reason I'm letting something slip through my fingers.

Lighting seems to be a "dark" place to one adventure himself. Albeit the large number of OpenGL tutorials into the Internet, I'd not found anything deeper than "the lit sphere" cases...

My time on Cryptex 3D is becaming scarce also, as some professional duties are taking precedence over it.
