The cool thing about 3D on small screens i.e. cel phones, digial picture viewers like the Fuji Film unit (and we hope the new mobile tv devices like flow tv), is that the combination of a single viewer and a small image makes determining a 'sweet spot' for glasses free viewing possible. This is fantastic for 3D - it allows our media to appear in many more venues making it a true media-type rather than just a specialty only for the big screen / glasses required experience.
3M is at the forefront of this technology and there is a great article on their Vikuti film here on geek.com:
