    I've played with that feature a bit.  The rendering times are very short
for scenes with mostly particles, since not that many pixels need to be
shaded.  As for the results, you may have already seen some of the early
tests.  For example, on the AmigaWorld animation tape there is a film called
"March 1989 Demo Reel" which contains a scene of a Voyager spacecraft flying
toward a gas giant planet with some moons.  If you watch the stars, you'll
see them blur properly as the camera pans (I set the camera shutter time to
be half the frame time).  Another example is the explosion of the NewTek
logo in the Penn & Teller video, in which it gets blasted into 2001 sparks
that leave trails and fade out.  In the future I plan to simulate rain and
fountains with LightWave's particles, as well as do more fireworks.
