Camera mounted on a slidebar
The easiest way to make stereo photos is to make the first picture, move the camera about 6cm to the right and make the second one.
It is important that you don't rotate the camera, nor shift the camera up or down.

Free hand taking of pictures is not that easy.
I build a slidebar for a tripod to enshure the pictures are not shifted or rotated wrong.
The slide bar is constructed of two extraction rails for drawers.
I bought them in a local hardware store and mounted them side by side.
An advantage of this method is that you can easily make photos with different stereo bases.
The disadvantage is that there may be no moving object in
the scene.
If there is a person on your image it may keep still untill the
second picture was taken. Clouds or water are also a problem.
The camera on this slide bar is an old Kodac Retina IIIc which makes still quite good pictures.

I took the pictures below to test the slidebar just after its completion (The Camera was a Nikon F80)
You need red-blue-glasses 
to view them... (click on the thumbnails to enlarge)
Some more pictures. (they are quite large, about 500k each)
I took them on a trip to the Netherlands (June 2002).
