Hello all.  I've been reading the list with interest.  I'm a DnD'er who is
interested in leaving what has become a bit of a jaded campaign and heading
for the stars.  Spelljammer just wasn't quite it, I'm afraid.  Now, if only
I could find some classic Traveller in the shops here...

Anyway, my contribution for what it's worth:

A similar device was used in the computer game "Elite," although it was
used to track other ships in 3-D space.  This was very useful and corrected
with pitching and yawing of the ship, so that you were always oriented with
respect to the other ships who had you in their sights.  It was not
particularly useful for gauging distances, but it seems to me that this
sort of thing is certainly amenable to fixed stars and could well be
adapted.  We already use a PC for our games simply for ease of rolling dice
and running the mechanics of large NPC companies, so adding something like
this if it were available would fit in easily.  I'm not a computer guru,
though, so it will have to be up to somebody else out there!

I now return to list-lurking and return you to your regularly scheduled
programme of informed correspondents.
