 As George remarked, a chalkboard would be a nice addition to the list. Since 
embedded graphics is frowned up, members can still "step up to the 
chalkboard" by making a diagram and posting it to a web site (any web site) 
and inserting a link here in list mail.
 It would seem that a simple diagram, done to scale and showing the positions 
and angles involved, would show the actual change in the observer's position, 
which in turn would show the actual shift in parallax that is or is not 
involved.

 [Personally I prefer the phrase "shift in parallax" rather than "change in 
parallax" as I have heard the former used to refer to a change in the amount 
of one parallax, as opposed to the broader realms of "changes".]
