There is still a functioning Camera Obscura in San Francisco.  It is located at 
the Cliff House near Ocean Beach.  While it does not have a true stereo effect, 
the concave shape and size of the table on which the image is projected gives a 
panoramic feel that approximates 3-D (for me) when the image sweeps across (as 
the lens/prism at the top of the room, er, camera, rotates 360 degrees).

What makes this one even more interesting, though, is that around the room, uh, 
camera, there are several holograms with tiny spotlights on them to keep the 
light level low so that the Camera Obscura's image is not diminished in its 
impressiveness.  Some of the holograms are quite good, but you have to be a 
certain height to appreciate them (unless you are with a friend willing to give 
you a boost).  And, for a tourist city, the cost of $1 for this tiny show is a 
pretty good value.
