[ "Send lawyers, guns, and money ..." ]

Well, I finally got a look at Dave Wecker's *incredible* pictures ... WOW!
Can't wait to see the new ones he just posted  ... thanks alot, Dave!
I'll be keeping a sharp eye out for the generating s/w that you mentioned.
That ought to give Amy something to be doing while I'm at work (sure hope
the raytracing s/w will multi-task :-) ).

I am curious about one thing in the "glass.img" though.  There are two
small white circles (one in front of the orange ball;  one next to the
blue ball).  From the shadow and highlighting effects, these appear to
be light sources.  What I'm wondering is why they both seem to be "flat",
with no "shading" or "contouring", whereas everything else looks "solid"
and has "depth"?  Is this effect intentional, an artifact of the raytracing
algorithm, or what?

Also, I wanted to mention that I have GRABBiT and AnyTime from Discovery
Software, and was able to use both of these resident utilities with Dave's
pictures.  GRABBiT dutifully dumped IFF formatted images into my GRAB:
device (I have it in RAM:), and AnyTime would pop up a 16-color palette,
and let me twiddle any of the 16 base colors, and the associated HAM
colors.  I didn't have a chance (yet) to redisplay the file that GRABBiT
dumped with SeeILBM, etc.  "Nice job" to Discovery Software, for providing
a couple of very useful utilities!

I should mention that I *did* hang the machine up the 1st time I tried
to save the screen ... I think I also tried to bring up the color palette
from AnyTime before the screen got saved, and that blew something (even
to RAM:, saving the 96K that "glass.img" becomes in IF format takes a
little time :-) )!  Ah, well ...
