is a stunning website filled with old articles from various publications from the 30s to the 60s. A gem I found is this one about a planetarium show at the NY Hayden planetarium in the 30s?. It deals with the effects for this show that detailed the impact of a meteor on the Earth.
One of the more amazing ideas was to use an arc lamp of high intensity and to project an image of the Moon thru a pinhole instead of a lens. By displacing the projector and slide one could make the image zoom out to giant proportions on the dome without the need for a fisheye or a follow focus mechanism. The small aperture of the pinhole would allow for sharp focus over the length of travel of the projector. There also is a "rain" projector on these pages. Go and check the original at the above URL, there is a search engine where you can type in the word "planetarium". It will bring these articles out.
