Let me say it again.  A very good facsimile display of a true color image can
be obtained using only 4096 colors.  Period.  Mach Banding?  Add random noise.
Make the display wider and taller, not deeper.  Use a better monitor.

Like I said, if you have a clue about the human eye's psychometric color
response, you can do a lot of interesting things without having to go to
a brute force solution.

You still really want 24 bits?  Better get a blitter with a hell of a lot more
bandwidth than the one we have now.

Kim already asked me that question.  I was basing my statement on the fact
that 24-bit frame buffers for "serious" computers (like one that we're in
the process of checking out) cost in the $5000 price range or more.  Granted,
we're talking higher res., but memory is cheap.

I'll believe the $700-$800 price tag for the Mimetics 24 bit frame buffer when
my dealer has one on his shelf.  I don't think they can sell it that cheap and
make a profit.  Remember "economy of scale."  At 640 x 400 it's still gonna 
have aliasing problems.  I'll take 1280x1024x12 over 640x400x24 any day.

If you were on the East Coast, I'd invite you to come visit me and look at
the display on the Eikonix Designmaster 8000.  12 bits and very impressive.

YOW!  I'm having visions of HIGHER SPATIAL RESOLUTION!!
