Sure, basic stereoscopic images can be created using software to merge two slightly offset photos, but that only works for stationary subjects. For moving targets, there's Fuji's Finepix Real 3D W1, or this $20 hack using two Canon PowerShot cameras.
Maximum PC's how-to uses 3D picture synchronization software called StereoData Maker, a nonvolatile firmware update based on the Canon Hack Development Kit (CHDK).
You'll then need to build a mounting rig, and use a small enclosure (such as an Altoids tin) to make a simple USB switch remote. Free software called StereoPhoto Maker is used for post-processing. And yeah, you'll still need a pair of red/cyan glasses. Still, it looks like fun. Full instructions at: [Maximum PC]
