Actually, I just tried it with photons on and it did not get rid of the
speckles.  Also, I do not think the speckles are from the egg crate pattern
since the frequency is too small and since this program does not seem to take
into account interference of waves, I don't think it would be possible to have
such a small frequency developing.  The reason I am being such a stickler with
this is that I plan on using this for visualizing an experiment and we would at
least try to minimize artifacts as much as possible.
