I see.  I think.  It appears to have some turbulence and if it's only
absorption I didn't realize that would be affected.  Unless it's the
refraction causing that.  Something I should try out anyhow.
caustics 0.5 perhaps, but no way of being sure what's best.  From what I've
seen of it before if too low a number is used the faked caustics spreads too
far and is faint (don't take my word for it) and if too high a number it is
too small and tight an area but not always brighter.  I've seen caustics 1
work out well many times and others not well at all.  I often raise the
diffuse of the object being projected onto so that it's more effective but
that can tend to mess with the texture your actually wanting (in this case
the table top).
