I was in a store the other day watching an A3000 running a Commodore-supplied
demo.  Not too bad; it was comparable in style to the typical demos you see
running on PClones.  Could've used some more impressive animations, I thought,
but hey.

Anyway, the demo did a couple of things where it would pull down its screen to
reveal a HAM picture beneath.  The downward movement of the front screen
did not appear to be completely smooth.  Later, a random customer was watching
the demo and asked why it "flickered".  I didn't really know what he meant,
but the salesman replied "It's the monitor".  The customer replied "It looks
pretty nice overall, except for the flicker."

This got me to thinking of a couple of questions:

	1)  Why was the screen movement not smooth?  I could only think of
	    two possible reasons:  programmer incompetence or the deinterlacer.
	    Could the deinterlacer have an effect?

	2)  In many programs, a screen is made to fade to black.  The fade 
	    never really looks smooth.  My only guess would be that 4 bits
	    for R, G and B just isn't enough, and that each change is very
	    noticeable.  Has anyone ever been able to effect a really smooth
	    fade of a color image?

"It's the monitor".  Sheesh, what a yoyo.
