brian@arl.wustl.edu (Brianosaurus) has a problem with his Newton computer.

Problem:
--------
OK.  Call me crazy.  Perhaps I was delirious last night while playing
Solo on my Newton, but is there some sort of mechanical click in the
Newton when you put a card in one of the four spots (I forget what
they're called) on the top?

I swear I hear this little thump, and it doesn't sound like its coming
from the speaker.


Answer:
-------
What you are experiencing is the LCD equivalent of the "Ka-Dink Effect."

The Ka-Dink Effect, as we all know, is the result of the electron streams
that trace along your computer monitors (and all CRTs actually) to display
images.  The electrons bounce off the glass in front and make a noise
that, played back slowly, sounds like "ka-dink!"  Of course, at the speed
that this normally occurs, the individual "ka-dinks" can't be separately
heard.  What is often reported is a sort of high pitched whine emanating
from the monitor.  This is actually a result of millions of "ka-dinks"
occurring every second.

In the case of the Newton, you are probably hearing the lesser-known
"Ker-Splash Effect."

When a dark area on the LCD is moved, a large number of the liquid crystals
must be carried to the new position on the display.  In "Solo," when you
drag the cards across the screen and drop them, you hear (and possibly
feel) the liquid crystals falling back into place.  This results in a sort
of "splash" sound.

The existence of the "Ker-Splash Effect" as well as the "Ka-Dink Effect"
is a widely disputed issue which has resulted in a handful of small
skirmishes, at least one holy war, and the bruising of one individual's
lower left arm.  However, I think that you would agree, given your
experience, that this condition actually does exist.

If you wish to learn more about this subject, I suggest that you read
