----------------------------Original message---------------------------- 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? XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX Dr.Iain C.

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.

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. vh
