Stereo cameras are very cool. I remember when I was a kid my best friend's dad was a professor at Yale Forestry. They used to take aerial stereoscopic images of forests and such, and he would take us to look at them. It was really cool to look at them through the little viewfinders -- they looked so 3D. I might give it a try someday if there is an easy way to do it.
I studied air photo interpretation as part of my geography minor in college, so I spent a LOT of time looking through those little viewers!
The way aerial stereos are made is about as simple as it can get: They just use one camera, and shoot two frames a short interval apart. The forward motion of the plane provides the necessary stereo separation. There's no reason you couldn't use the same principle by shooting out the window of a car, for example, although it might make subject selection a bit restrictive...
