Lytro demonstrates features that could be used for 3D

Lytro is the “light field” camera that enables the photographer to adjust focus long after the image was captured. This means changing the depth of field after, not before, taking the picture.

Watching this demonstration video of Lytro’s perspective shift capability, it is a small step to using this to create stereoscopic-like 3D images from an individual Lytro photo:
