Basically, I agree with you.  The highlight position or shape won't
change and it won't get bigger, even though the light source is now
bigger.

	But, the block_area_light function basically figures out how much of
the area light is visible from any point and multiplies the phong or
specular or whatever highlight by that percentage.  This is totally
visible in this post.

	However, you can still see that POV cheats!  The sharp shadow line on
the second sphere wouldn't be there in reality, because part of the
light is still visible over the horizon.  There should be a smooth
transition.

	Well the idea works, but it looks like a 1:100 sun won't do anything
for you.

In Him,
	Ben
