Wiggle 3D - Stereo 3D photographs without a need for glasses

I saw some stereo photographs, that's 3D but with no need for 3D glasses, and I'm fascinated. I want to do this. When ever I get the time of course. The idea is simple, take a photo, move the camera slightly, take a new photo. Then add the photos together in an animated GIF. Nothing's that simple though and I'm expecting a lot of tinkering and editing to get it to work.

I've found a page at Adorama with a How To that explains the process and gives advice about what to think of. Now all I need is time.
