     I first saw one of these in a display case at the Lowell Observatory in 
Flagstaff.  It just so happens that it was there that Neil Armstrong made his 
last public appearance at the dedication for a new observatory built by the 
Discovery Channel.

     And then there was this mechanical wonder from the early 1960's:

     I had one of these.  It tended to get stuck when you operated the slides, 
but it was still pretyy neat.
