I went to a conference in Pasadena this weekend, which finished late 
Saturday night, and thought I'd spend time Sunday looking around the 
area. I realized I hadn't gone to Griffith obs. for almost 30 year, so 
managed to get there with not a lot of time in the day. I knew it had 
been modernized, and so it was. They had a clever display of the Big 
Dipper in a plastic transparent ball about 8-10' in diameter. Inside 
they had about 15 glowing balls of of varying brightness. The idea was 
to walk around the ball and find where the perspective was the BD. Quite

good. I wouldn't mind building something on a smaller scale for our 
little museum, without the globe. I think I saw something along these 
lines on the web some years ago. Comments?

I'll have to go back there some day, and get a better look at 
everything. It was quite an improvement. Perhaps I'll go to Mt. Wilson 
too. I know it's become a big interferometer, but don't know anything 
about the public buildings there.
