Related to this is the 'orrery' -  (the word has an interesting entry in the
OED!).
 
I saw an Earth, moon, sun version produced in this century with a miniature
earth globe by Phillips of London & Liverpool.  It was a complex clock-like
mechanism that showed in an analogue way exactly the area of the earth lit at
different times and seasons. The brass rim gave the months of the year.
 
Does anyone know of a good reference book or article on these?  Are they still
available?

I've seen clocks that did this but never a map. I'm sorry I can't tell you where
to get one of the clocks
but they aren't too hard to find - it seem that any map store or earthy type of
gift shop could help you out.
 
If I recall correctly they are about $1500 - 2000 and real popular with CIA and
DOD types who have to
worry about this sort of thing.
 
Now that I think of it - it seems that I have also seen software that would do
the same thing on a computer
screen.
 
Sorry I have no better advice.
 
Good luck,

The really most clever thing would be to go to the Maparium at the
Christian Science mother church in Boston.  Absent the money to
send your patron to Boston, I'd suggest looking at the various
software packages that produce "3-D" looking maps such as Surfer.
You might also want to check with the UW Madison or UW Milwaukee
Geography Departments for help.
