I'd love to see a picture of this exhibit.  Anyone have one?

I went to a conference in Pasadena this weekend, which finished late=20

Saturday night, and thought I'd spend time Sunday looking around the=20

area. I realized I hadn't gone to Griffith obs. for almost 30 year, so=20

managed to get there with not a lot of time in the day. I knew it had=20

been modernized, and so it was. They had a clever display of the Big=20

Dipper in a plastic transparent ball about 8-10' in diameter. Inside=20

they had about 15 glowing balls of of varying brightness. The idea was=20

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=20

little museum, without the globe. I think I saw something along these=20

lines on the web some years ago. Comments?



I'll have to go back there some day, and get a better look at=20

everything. It was quite an improvement. Perhaps I'll go to Mt. Wilson=20

too. I know it's become a big interferometer, but don't know anything=20

about the public buildings there.
