This seems kinda cool, I'm going to give it a shot.<ul><li><a href="http://wiki.ehow.com/Create-Stereo-Photographs">http://wiki.ehow.com/Create-Stereo-Photographs</a></li></ul>

Just shoot your scene, make a move to either side, and take another shot aiming at the same.

In post production, crop to match equal content. Done.

I've done this to the extreme of giving it an extended base (far wider than the human eye distance) and got mind-blowing results. Play with it and experience yourself.

If you have two cameras and can synch them, you can go for moving targets (playing children, e.g.) and get even more flabbergasting results.
