I think that’s cabbage behind the cat. Here’s some directions on how to view stereoscopic images with just your two eyes.
One of the New Year’s resolutions I forgot to mention is to put together an evening of stereoscopic images and present them (with suitable glasses) at a local venue.

I imagine that you are aware of the National Stereoscopic Association and their great publication, Stereo World http://stereoworld.org/
I’ve never been able to do the stereoscopic thing with just my eyes – I always end up feeling a little dizzy and headachey, but I do find it really interesting. At the risk of dating myself, I was once the owner of a Viewmaster and an impressive collection of disks for it.
A couple of years ago, I invested in my own copy of “A Village Lost and Found” by Brian May, whom all of you in my age group will recognize as the guitarist of Queen. A most wonderful book that is fascinating to anyone interested in 19th century rural England, rural life in general and stereoscopic photographs, well worth every penny. Fortunately, it comes with a viewer so my eyes don’t go all funny on me. There’s an extensive section about how stereoscopic photography works and lots of history, biographical information about the photographer, T.R. Williams, modern photos of the village – just a wonderful read.
Here’s a link to an interview Terry Gross (“Fresh Air”) did with May, during which they talk about the book: http://www.wbur.org/npr/128935865/queens-brian-may-rocks-out-to-physics-photography
