Hi Dan, I have watched this thread, but seen nothing
on the visual benefits of a moving image or moving
matrix.

One of the reasons a telephone system can use a very
low res video image is that the person's face MOVES,
this increases the level of detail by an enormous
amount when viewed by a human at least. :o)

You might be surprised, if you moved your hi-res
snail image a couple of pixels to the right each
frame, then reduced it to 10x10 pixels, then
join these images together into an animation.
As the picture moves right and left you will see
all the fine details come to life in your 10x10
animated image.

This works pretty good looking at faces on TV that
have been "pixelated out", to hide their identity,
especially if their face is moving, squint your eyes
and you can see them pretty good. I noticed now
some programs are starting to use VERY coarse
pixels for this face masking...
