Oobject has collected several photos of planetarium projectors, which are wonderfully elaborate machines.

Their purpose is a bizarre reversal of a large optical telescope, taking an internal view of the the universe and projecting it on a dome, rather than creating a view from peering outside of one, but the aesthetic is somewhat similar. Another curious similarity is how much they look like some early satellites.

Some of these look like huge drills.
