Kevin old sport, you show me an image that trasitions from (0, 0, 0)
to (0, 0, 15) SMOOTHLY, without any wierd dithering artifacts, and I'll
believe you when you say 4096 colors is enough. I havnt been able
to acheive this however...

I think the question is not really the number of colors, but the width
of the dacs. 4096 shades of blue would be just fine thank you, but 15
shades of blue is just too course. Yes, we've tried mach banding, and random
noise and dithering (hmm, maybe should have tried 'time domain dithering' :-)
and the conclusion is we'd like 'colors that are closer together'; there
is just too much of a difference between (0, 0, 7) and (0, 0, 8).

I've seen the Eikonix stuff at shows, it's real nice. So how do you do
it, eh, Kevin :-)
