You can make stereograms with your Lytro, but you're limited to center to center distances less than the diameter of the lens. I was surprised when the Lytro came out and it was so tiny. To be properly useful, it needed about a 10" diameter outer lens. There are ways to take multiple conventional exposures from the same plane, and generate a virtual focal plane after the fact. I've been manually doing that (using Hugin and a python script) since I heard (in 2008) of Marc Levoy's experiments at Stanford.
