Why not set stereo mode to cross eyes and visualize that way? Requires
no additional hardware and is quite easy. I'm sure you can find a good
tutorial for viewing that by googling cross eye 3d or somesuch. The
main idea is to cross your eyes in front of the screen and superimpose
the right eye's image of the left screen image with the left eye's image
of the right eye's image (such that the path of the line of sight of the
individual eyes crosses, hence the name). It takes a bit of trying, and
some people find focusing on a finger held in the middle to help initially.
