	Along these lines, I've been thinking that it may look very good to
change the lighting depending on the viewer's location.  What I'm suggesting
is darkening the lighting of indoor areas the viewer can see into from
outdoors, and brightening the lighting of outdoor areas the viewer can see
from indoors.

	As the viewer crosses a boundary from outdoor to indoor, the indoor
and outdoor lighting can be brightened until the indoor lighting is at the
"normal" light level and vice-versa.  I'm not sure whether this can be
achieved through gamma correction.  Are configurable gamma ramps supported
on most major 3D accelerators?  I know I can change the gamma on my nVidia
cards, but my older 2D card (an SiS 3D deccelerator) didn't respond.
