Actually, what you are doing is far more sophisticated than the sky
effect in the pictures. Judging by the description given here, the sky
effect is only capable of brightening or darkening a pixel's original
color. The sky effect would be simple to duplicate in POV, but would be
unable to give the effect of bright light shining through a window, or
of a flashlight beam pointed a the viewer. Your process, Tim, appears as
if it could accomplish these things once you get the color recognizing
bit coded in. What neither could accomplish, however, is something like
a bright light shining through a chain link fence, because both use
blurring when proximity is actually what you are attempting to simulate.
