Larry B's animation

[P3D John Bercovitz <bercov@xxxxxxxxxxx>]

That's a pretty darned good animation, Larry!  I think it 
shows that if external clues nail the window to something,
such as a screen, it _is_ easier to imagine that infinity is
moving than to imagine the window is moving.  I can see it
either way but the stationary window is much easier.  Now 
if you don't have the window nailed to something that is
physically apparent, in other words if you have an RB and 
you change aperture separation, or if you have a very dark 
projection room and do the same, I think it will be easier 
to imagine the window moving towards and away than to imagine 
infinity moving towards and away.  With NSA looming, I'm
not going to have a chance to try this for a while.  8-(

Certainly racking the horizontal control on a TDC back and
forth doesn't do much but that's not the same thing as moving 
chips relative to their apertures which is what we're discussing
in this particular subthread, I believe.
