:D I'm with you on gross arm movements, I'm just trying to expand the code-viewing experience beyond "strings stacked on top of one another"
While all the VR goggles try to embed your body into virtual space (putting the graphics "around you") I'm prototyping with a stereo-microscope, with it's nice heavy knobs for course and fine adjustment, such that you're looking into the virtual world from the outside. No illusions to pull off, no motion sickness, and nothing strapped to your face.
