Looking at creating 3D Stereoscopic photos

When I was a child I had one of those 3D photo viewers, I was totally fascinated with it. My enthusiasm hasn't really faded there and I have always wanted to do something like that. I recently purchased a couple of identical sony cameras for a second hand store. I am in the process of setting them up to take stereo photos. I have tried some experimental photos on some still life objects ant the results are promising, I would like to take some 'real life' action type photos.
